Effect of changing strain rate on flow stress during hot deformation of Type 316L stainless steel
This paper developed the world-first constitutive equation which quantifies the effect of changing strain-rate on flow stress during hot-rolling for 316L stainless steel. This alloy is difficult to machine for it requires low speeds and constant feed rates in order to circumvent the phenomenon of work-hardening. It is corrosion resistant and is extensively used in the manufacturing of jewellery/medical implants, as well as in marine applications. The study, whose findings can be extended to other similar alloys, is particularly important as it leads to significant improvements in hot-working, which requires optimisation within 1150-1260 Deg.
