These have been found to display an optimum combination of properties such as high strength, good bend ductility, improved corrosion resistance and excellent soft magnetic properties. Thus, metallic glasses are emerging as economically viable competitors to conventional engineering materials. A clear understanding of the atomic structure of metallic glasses and its change during annealing are of prime importance. Although techniques such as field-ion microscopy (fim) x-ray diffraction and small angle x-ray scattering have been employed for this purpose, high resolution electron microscopic (hrem) investigations conducted during the last few years aided greatly in deriving information on the atomic scale. Availability of high-voltage high-resolution electron microscopes has been mainly responsible for this happy situation. Studies on several metallic glass...

Feasibility of such a goal can be carried out, at laboratory level, by any milling device like the very common planetary all mill. In this case however, the possibility of of subsequent scaling up for larger production is hindered by the intrinsic limits of planetary ball mill design. On the contrary the horizontal Simoloyer can be experimented at laborator level using small volume chamber-units (0.25, 0.5, 2 l) and, for industrial produdion, using the large volume units (up to 400 l) based on the same conceptual design. Therefore, experiments have been conducted on blended elemental Ti-24Al-11Nb (at%) powder using a simoloyer with a small unit-chamber (0.5 l). Due to the inherent ductility of the powder, the material has the tendency to adhere to the grinding unit and the steel balls. Further, in order to avoid high contamination and to make the process realistic from an economical point of view, the milling time has to be reduced to a minimum. The above points identify a Critical Milling Behaviour (CMB) of the system under investigation that must be kept under control to achieve the wanted goal. It will be shown that by adopting a suitable milling and discharging procedure low contamination and good yield have been substantially achieved with respect to preliminary not unambiguous trials carried out at Idaho university.
