Plastic Instability in Co-Cr-Ni-Mo alloy wires drawn with different drawing practices by GVK, Sai Srikanth, Tan, Ming Jen, Liu, Zhenyun

“…The lower instability in the FDD wires at 75% CW, was attributed to the smaller grain size, higher dislocation density and lower twin spacing which contributed to higher γ and m. Plastic strain localization because of shear band formation was noticed in the FDD 95% CW wires, which contributed to lowered ductility and increased instability in the wire due to reduced γ and m. …”
