Abstract
The hot deformation behavior of medium-carbon Cr-Mo alloy, which has been developed for high strength cold-heading quality wire rod, was investigated to evaluate its hot workability. A flow curve was derived using the hot torsion test, under conditions with temperatures of 1173-1273 K and strain rates of 0.1-1.0 s^-1. At..... More

Abstract
Torsion tests were performed on AA6082 samples to investigate their flow softening behavior and to determine optimum process conditions. Based on the experimental data and dynamic materials model, high strain processing maps were established which demonstrate the constitutive relationships among temperature, strain rate, strain and stress. The flow curves exhibited..... More
