چکیده
Experiments were conducted to evaluate the evolution of stored energy in grains with shear texture orientations A1* {111}<1?1?2>, A2* {111}<12?1>, A {111}<11?0>, A? {111}<01?1>, B {112}<11?0>, B? {112}<11?0>and C {100}<110>for Cu-2.5Ni-0.6Si and Fe-36Ni (wt%) alloys after high-pressure torsion (HPT) processing up 10 turns at ambient temperature using a Kernel Average Misorientation (KAM) approach. typical stable developed alloy immediately 1 turn whereas there was continuous transformation turns. The results show that HPT produces similar energies ~35 J/mol ~24 but different components for alloy, respectively. all increases increasing then slightly decreases through By contrast, continuously numbers These evolutions are examined reference initial textures, dynamic recrystallization, grain refinement mechanisms differences stacking fault energies.
