Abstract
The structural changes in mechanically mixed metals of immiscible combinations of elements caused by bulk mechanical alloying (MA) through the use of high pressure torsion (HPT) were investigated in Ag-Ni and Nb-Zr systems. There was no alloying between Ag and Ni on atomic scale even after 100 rotations of HPT. On the other hand, the beta-Zr phase started to appear after HPT 2 rotations in the Nb-Zr system, even though beta-Zr is a high temperature phase. Further, Nb and Zr were completely mixed to form a bcc structured single phase after HPT 100 rotations. The sequence of alloying in the Nb-Zr system during HPT was discussed. These results clearly suggest that non-equilibrium phases can form in the Nb-Zr system by bulk MA by the use of HPT.
