Aerospace and space industry has traditionally been a pacemaker for development and introduction of new materials systems and production technologies. The key driving forces for materials development are weight reduction, application-specific performance improvement, and reduced costs. Application of advanced engineering materials has significant impact on both economical and ecological issues.
Aerospace Materials Research Opportunities
Angewandte Chemie, 1989
As we approach the second century of aerospace, increased emphasis is being placed on endurance, reliability, ease of manufacture, and lower cost, in addition to weight saving. This change in emphasis will have a major effect on not only the selection of materials, but on how materials are integrated into the total system design process. Subsonic aircraft will continue to play a major role in our future with emphasis on increased durability and lower cost. .Nonmetals that do not corrode are attractive; however, the issues of reliable fracture resistance to ensure safety and durability as well as ease of manufacture and inspection will be key. Higher performance engines and hypersonic aircraft will require higher temperature materials (including a substantial amount of non-metals) along with reliable toughness and ease of manufacture. In space, weight will continue to be a major driving force along with the need for long term vacuum and radiation stability. Ease of assembly and multifunctional use (e.g. electrically or thermally conducting structure) will be additional needs for spacecraft materials. We have reached a point in the evolution of structural materials where we are moving away from processing naturally occurring materials toward synthesizing designed microstructures to perform specific functions. The mathematical modeling of microstructure-property relationships and new chemical and biotechnical synthesis techniques appear to be critical technologies for the future. In addition, the future materials developer will need a broader understanding of the total structural life cycle so that the impact of utilization, maintenance, and training requirements in the design of new materials can be considered.
Evolution of Aerospace Materials: A Review
IRJET, 2022
The choice of materials used to construct an aircraft is of paramount importance due to several factors, such as safety, structural integrity and weight optimization. In this article, the evolution of materials that are particularly used in the aerospace industry since the beginning of last century is reported. This report will review the different materials that have been used in the aerospace industry since its inception. They include, but are not limited to, metals, plastics, composites, ceramics and glasses. With the development of new materials technology, aerospace engineering has quickly become one of the fastest growing industries and it is only set to continue to grow exponentially with innovations like 3D printing and nanotechnology. Alongside other industries like automobile engineering and locomotive manufacturing, aerospace engineering has benefited from such developments which have also helped increase space travel. Research is being conducted on materials that are designed to have excellent properties, including high strength/weight ratio, easy manufacturability, and corrosion and heat resistance. These materials would be suitable for aircrafts and offer a variety of benefits.
Materials used in the combat aviation construction
Transport Problems, 2021
In this work, an attempt was made to apply laser surface technology for enhancement of the properties and strengthening the material with addition of ceramic phases in the form of silicon and tungsten carbide particles, leading to a remarkable increase in hardness. Thanks to rapid cooling caused by heat being transferred to the cold substrate, an advantageous, fine-grained structure develops, showing higher gradient morphology; furthermore, the surface layers obtained with laser alloying offer greater heat-resistance and anti-corrosion properties, as well as high wear resistance in addition to the aforementioned hardness, which increases by as much as 15% for the AlSi9Cu4 alloy compared with the alloy after standard heat treatment. Such an increase in the values of the mechanical properties makes it possible to use the investigated alloy in applications including, e.g., recyclable thermally exposed surfaces, such as pistons in internal combustion engines, which enables further decrease in the weight and the thermal expansion with simultaneous increase in the strength, reduction in fuel consumption, and increase in carrying load, speed, and range, which generates the need for further research into the area.
Fusion materials development program in the broader approach activities
Journal of Nuclear Materials, 2009
Breeding blankets are the most important components in DEMO. The DEMO blanket has to withstand high neutron flux typically 15-30 dpa/year under continuous operation. Therefore integrated and effective development of blanket structural materials and breeding/multiplying materials is essential in the blanket development for DEMO. In parallel to the ITER program, broader approach (BA) activities are initiated by EU and Japan. Based on the common interest of each party towards DEMO, R&D on reduced activation ferritic martensitic (RAFM) steels as a DEMO blanket structural material, SiC f /SiC composites which have potential for use in DEMO blankets, advanced tritium breeders and neutron multiplier for DEMO blankets, and tritium technologies including tritium behavior studies in advanced materials for DEMO blanket applications will be carried out as a part of the BA activities.

Ballistic studies of lightweight materials -a review
Journal of Mechanical and Energy Engineering, 2020
A recent development in the material studies provides beneficial application of lightweight alloys such as aluminium, magnesium as well as composites and metal matrices. The alloys are experimentally improved by increasing hardness in the ballistics testing using projectiles, makes them viable for the areas such as aerospace, military, defence, automobiles and so on. So the study is made on different approaches. First, by comparing different types of non-ferrous alloys and projectiles regarding sizes, structures. Second, the materials with heat treatment are also studied for investigating the hardness property by overcoming successful penetration on non-ferrous alloys. Third, material to be improvised by use of numerical studies such as 3D models, empirical models and software such as ANSYS, ABAQUS and AUTODYN, etc. Finally, the aim of this paper is to review the recent progress ballistic studies of lightweight materials and to provide a best choice of material for further ongoing research.
A Review of Properties of Advanced Aerospace Materials
The use of advanced materials has always been a key element in the success of aerospace industry. Aerospace components should have damage tolerance characteristics with high resistance under both static and dynamic loads. To meet the specific requirements, new materials have been necessary to improve and advance aviation. This improvement will come from advances in synthesis/processing of materials. These advanced alloys are more demanding in terms of machinability as their structure and material properties are focused on improved resistance to dwell crack growth, environmental damage and creep strain, as well as higher levels of microstructure stability and high temperature yield stress. Modern machine tools with advanced machining processes are key enablers to achieve overall quality and productivity goals to meet future market requirements. In this paper, properties of advanced materials in general are discussed; specifically advanced materials in aerospace applications.
