The main characteristics required for such applications are high compression resistance, microstructural stability during thermal stress, hardness and corrosion resistance. To obtain such specific characteristics, the raw materials must be melted in inert protective atmosphere, and then heat treated for the homogenization of the microstructure and chemical composition. In the paper, there have been studied three types of high entropy alloys, HfMoNiTaW, 2HfMoNi2Ta and MoNiTaW obtained in the vacuum arc remelting (VAR) equipment. The heat treatment, performed at 800 o C with a holding time of 4 hours, allows obtaining a good homogenization of the chemical composition while generating a decrease in the microhardness, from a maximum value of 637 HV0.2 to a minimum value of 527HV0.2.

The alloy was obtained using the vacuum arc remelting (VAR) technique in MRF-ABJ900 equipment. The microstructural analysis was performed by optical and scanning electron microscopy (SEM microscope, SEM-EDS) and the phase transformations were highlighted by dilatometric analysis and differential thermal analysis (DTA). The results show that the as-cast alloy microstructure is three-phase, with an average microhardness of 487 HV 0.1/15. The obtained alloy could be included in the group of compositionally complex alloys (CCA). The corrosion resistance was studied using the potentiodynamic method in saline solution with 3.5% NaCl. Considering the high corrosion resistance, the obtained alloy can be used for surface coating applications.
The explosive effect and high velocity penetration of the ballistic projectiles of various sizes,... more The explosive effect and high velocity penetration of the ballistic projectiles of various sizes, design and compositions, on impact with different targets (armors composed of a combination of different metals) are complex. Both practical experiments and mathematical modeling of the phenomena associated to the interaction projectile-target are required to estimate their effect or to design more efficient projectiles and armor. In this study, the basic element of the simulation model is an incendiary projectile of caliber 7.62 mm with medium piercing power, launched with a maximum speed of 750 ms-1 on the multi-material target, which contains 4 different layers assembled into a ballistic cassette made of aluminum. The purpose of this ballistic cassette is to ensure a better contact and handling of multi-layer materials. The proposed model was calculated using mathematical modeling and empirical material constants to describe the nonlinear transitory impact process. Mathematical simulation of the impact between the projectile and target during impact shows that the projectile moves sequentially through the ballistic package, causing perforation, plastic deformation and heating, the resulting fragments being then expelled into the space around the target. The model indicates that the projectile will penetrate the front aluminum plate, as well as the AlCrFeCoNi and steel plates, but will be stopped by the aluminum backing plate. The real impact tests carried out using the ballistic cassette at dynamic impact with the 7.62mm incendiary projectile confirm the model assumptions, which prove the capacity of the composite model to safely stop the projectile. The simulation and modeling methods allow the qualitative and quantitative study of the most complex mechanical, physical and chemical processes and phenomena. Through them, the system dynamic development and behavior could be estimated. In the area of materials science, the simulations allow the researcher to determine the outcome of material-system interaction in dynamic conditions, such as the impact relation between projectile and target. Split Hopkinson Pressure Bar (SHPB) is the most widely used method to describe the results of different materials samples exposed to medium and high speed shaping [1-6]. The best described SHPB process induces unidirectional pressure in the target sample by the simultaneous opposing impact of two bars. The impact generates an elastic wave in the impacting bar which is partially transferred to the sample and partially reflected by the transition bar. Sensors installed at the ends of the bars measure the generated energy, and the results will allow the shaping of the energetic phenomena and the estimation of the generated forces. The SHPB method has data accuracy shortfalls related to noise level, characteristic wave length dispersion and a number of other specific characteristics [7-9]. The professional publications have dedicated extensive attention to the phenomena and processes arising during armor piercing projectile impact with materials of various compositions. Such research is focused on various types of high impact perforator projectiles and projectiles fragments, as well as the behavior vs. various impact targets such as armed concrete, metal plates and composite structures. The mathematical simulation using a limited number of preset characteristics, offers the possibility to study the impact and deformation process in real time and estimate the area of target crack by analyzing the depth of the penetration, calculate the residual speed of the projectile or fragments, calculating the deceleration profile as function of the initial launching speed. The characteristics of the impact area, cracks, craters and adjacent zones, are in general good agreement with the simulation data, leading to a good description of the complex interaction between the projectile and target [10]. An alternative to dynamic or static simulations is provided by compression tests. Static or dynamic compression tests permit the design and use of SHPB to study the deformation gradient at various values of temperature. Using lanthanum cylindrical specimens and employing the Johnson-Cook (J-K) equations, the specific deformation characteristics could be easily calculated. J-K compression equations calculated in the SHPB tests for lanthanum sample were calibrated through numeric simulations and the results confirmed large deformations when exposed to complex pressure tests. Based on the static and dynamic test results (MTS) using the pulling test on a divided Hopkinson lanthanum sample, the tractor J-K equations were calculated. The reflected and transferred wave of the PSHB tests resulted from the numeric simulation for lanthanum sample, using the speed of deformation as function of crack failure and was confirmed by the subsequent experiments. The relationship between the dynamic crack failure and the speed of tractor force was pointed out as critical. SEM analysis of the fractured surface showed the crack failure mechanism becomes erratical with increased speed of the applied effort [11, 23-24]. *

The effects of the proportion of each chemical element on the main characteristics of the alloy based on the mixture rule and the correlation between the melting temperature and the modulus of elasticity were analyzed numerically. The model results has reveals that even other factors must be taken into account, i.e. the mechanical characteristics which varied significantly with changing of chemical compositions. A compromise was set, by slightly increasing the density to acquire better mechanical characteristics. The selected chemical composition was then used to obtain the new low density alloy. In current research stage we conclude that the as cast alloy comprises an inhomogeneous solid solution and complex oxides. Further studies are ongoing on the experimental alloy in various states (homogenization annealed and processed by plastic deformation). Light weight alloys are attractive for transport and energy industry where titanium alloys are the heaviest of this class used in engineering applications. Common structural alloys where weight is of main concern are based on a single principal element like Al, Mg or Ti. These conventional alloys have shown their limits and starting 2004 [1-3] a new class of alloys with excellent and customizable characteristics given by their unique composition and microstructure, named high entropy alloys (HEA) is developed. Although 15 years have passed since their emergence, these alloys are loosely defined by Yeh [4] as composed of five or more principal elements in equimolar ratios. The definition expands the range by specifying that the principal elements concentration can range between 35 at% and 5 at%. Minor element additions for properties customization are also accepted [5, 6]. Along high entropy alloys the concept of multi-principal element alloys (MPEA) is introduced by Cantor [1]. In literature the terms are used interchangeably, Miracle [7] uses the term HEA when configurationally entropy or single-phase solid solution are the intent. Since the aim of this research was not to obtain a Single-phase solid solution or the entropy, the terminology multi-component principal element is more adequate for the alloy analyzed in this study. The difficulty in raw material melting and procedural costs make HEA's currently inaccessible for large structural components therefore, using a similar approach, has been studied the possibility to obtain a low density MPEA from the Al-Mg-Ca-Si-B system, using Al as the base chemical element. There are know many aluminum alloys, but only several chemical elements are important as alloying elements in commercial alloys. The choice of alloying elements is based on the mutual chemical compatibility and the possibility of obtaining the best technological properties [8-29]. For the Al-Mg-Ca-Si-B system, the solubility of the alloying elements is shown in table 1. From the classical metallurgy point of view key aspects from binary and ternary systems are presented along the influence of each alloying element. The Al-Mg binary alloy * email: ioneliav@yahoo.co.uk, Phone: 0744-327991 system is complex: a eutectic appears at 35 wt% Mg at 450°C, a temperature at which Mg reaches its maximum solubility in Al at 14.9wt%. At room temperature Mg solubility in Al reaches roughly 1.7 wt%. The addition of Mg in Al has an effect in decreasing alloy density by 0.5% for each 1 wt% of Mg [7, 30]. In Mg-Ca binary alloys the microstructure is altered by Ca content: in as cast condition the dendritic cell size appears finer as Ca content increases (up to 10%) and MgCa 2 phase appears on grain boundaries [8-11, 24]. The Al-Si binary systems and Al-Mg-Si, Al-Si-Mg ternary systems are overviewed together. In binary Al-Si systems, Si forms coherent clusters in solid solution [12-14], Al-Si clusters in hypoeutectic alloys and primary silicon crystals in hypereutectic alloys [15]. In Al-Si alloys Mg is added for strengthening since the formation of Mg 2 Si precipitates occurs. From the Al-Mg-Si system the majority of the commercial alloys are intended for extrusion. Usually Mg and Si content is somewhat equal, 0.75w%t to 1.2w%t, but, by adding excess Si an additional response to age hardening by Mg 2 Si precipitates refining [16] is gained. High silicon content, 5 to 20wt% Si in Al-Si-Mg alloys creates best casting properties. In the Al-B system a eutectic appears at 660°C at 0.022 wt% B between Al and B 2 Al. Boron is mainly added to refine grain size or increase the electrical conductivity. The selection of the chemical composition of this MPEA proves difficult given the contradictory and various effects Table 1 THE VALUES OF SOLUBILITY IN SOLID AND LIQUID STATE FOR ALLOYING ELEMENTS IN ALUMINUM [8, 11, 15, 30]

A modified composition of AISI 316 stainless steel was treated using solar energy in a vertical axis solar furnace and it was subjected to a hyper-hardening treatment at a 1050 °C austenitizing temperature with a rapid cooling in cold water followed by three variants of tempering (150, 250, and 350 °C). After the heat treatment, the samples were analyzed in terms of hardness, microstructure (performed by scanning electron microscopy), and corrosion resistance. The electrochemical measurements were performed by potentiodynamic and electrochemical impedance spectroscopy in liquids that simulate biological fluids (NaCl 0.9% and Ringer's solution). Different corrosion behaviors according to the heat treatment type have been observed and a passivation layer has formed on some of the heat-treated samples. The samples, heat-treated by immersion quenching, exhibit a significantly improved pitting corrosion resistance. The subsequent heat treatments, like tempering at 350 °C after quenching, also promote low corrosion rates. The heat treatments performed using solar energy applied on stainless steel can lead to good corrosion behavior and can be recommended as unconventional thermal processing of biocompatible materials.
