Abstract

The effect of stacking fault energy on microstructure, micro texture and hardness evolution in Ni-Co alloys during severe plastic deformation by high pressure torsion was studied in the present work. For this purpose a series of Ni-Co alloys have been chosen as model alloy systems with composition of Ni-20%Co, Ni-40%Co and Ni-60%Co with decreasing stacking fault energies. These alloys were severe deformed by high pressure torsion (HPT) at room temperature to different number of rotations (N), namely, N=1/12, 1/4, 1/8, 1/2, 1, 3, 5 and 10 under an applied load of 5GPa.
