The occurrence of shear bands in isothermal, hot forging
S. L. Semiatin,G. D. Lahoti +1 more
TL;DR: In this paper, the occurrence of shear bands in isothermal, hot forging of metals has been investigated using a variety of experimental and analytical tools, and an instability criterion was developed, and the tendency to form shear band was shown to depend strongly on the ratio of the non-dimensional work-hardening (or flow-softening) rate to the strain-rate sensitivity of the flow stress.

Unstable flow during hot deformation of Ti-24AI-20Nb alloy
TL;DR: In this paper, unstable flow during hot deformation of an α2 titanium aluminide alloy Ti-24Al-20Nb alloy was analysed using two criteria, one of which was developed by Jonas and the other by Kalyankumar.
