摘要
An experimental procedure has been developed to investigate systematically the effect of initial grain orientation on the evolution of deformed microstructure in Ni-30Fe alloy. The investigation of identical grains before and after hot deformation made it possible to trace the evolution of microstructure deformed up to 50% at a strain rate of 1/s in a single pass at 1023 K using a hot compression simulator. The localized inhomogeneous shear bands occurred in almost all grains. On the other hand, the near {110}<001> grains have undergone fairly homogeneous deformation even after a high equivalent plastic strain of 1.9.
