The Flow Stress and Microstructures of Fe-1.6%Si Silicon Steel

Abstract:

The hot simulation experiments on the Fe-1.6%Si silicon steel were carried out at 900°C and 1200°C, stains of 0.4 and 0.8, and strain rates of 0.5S^-1 and 2s^-1 respectively. The maximum stress was 90MPa when samples were compressed in the case of 900°C and a strain rate of 2s^-1, and which was 30MPa at 900°C and a strain rate of 0.5 s^-1. The true stress-strain curve is characterized by dynamic recovery, and a pancaked ferrite microstructure with the average grain size of 378~660μm could be observed at the strain of 0.8 and 0.4 and deformation temperature of 900°C.
