Supersaturated Al-Ti-Cr alloys were produced by a continuous electron beam evaporation technique. The as-deposited alloy sheets were fcc supersaturated solid solution with an average grain size of about 400 nm. Due to the fine grain size, the hardness of the alloy was as high as 270Hv. The sheet showed age hardening, and the peak hardness of 340Hv was obtained after aging at 623K for 900 s, in ...

The pressure dependence of the lattice and elastic constants binary precipitates γ-TiAl, DO22-Al3Ti α2-Ti3Al are firstly investigated by using a first-principles approach. calculated results at 0 GPa K agree well with existing experimental other theoretical values. Using density-functional perturbation theory (DFPT) under quasiharmonic approximation (QHA), temperature dependencies bulk modulus, ...

The study presents the comparative analysis of compressive response for experimental aluminium foams different parent alloys fabricated by melt processing with/without Ca additive and an expensive conventional TiH2 foaming agent or a cheap alternative CaCO3. It was recognized that is significantly dependent on type due to formation low ductile brittle products created in process. presence defor...
