Evolution of the Zr42.5Сu42.5Al10Fe5 amorphous alloy structure during the HPT process

The paper analyzes the effect of severe plastic deformation on the structure, mechanical and thermal properties of a Zr42.5Сu42.5Al10Fe5 alloy. It was found that high pressure torsion induces phase separation of an amorphous matrix and causes formation of a complex structure containing nanocrystalline particles. The precipitation of nanocrystals leads to a change in the composition of the amorphous matrix and changes in the crystallization...
