Experimental technique to characterize the plastic behaviour of metallic materials in a wide range of temperatures and strain rates: Application to a high-carbon steel.

Résumé

This paper presents high temperature quasi-static and dynamic tensile testing. Samples are heated by an induction system controlled with a pyrometer. A high-speed camera (500 fps) is used to determine displacement fields with a digital image correlation software. For such tests a specific marking procedure of the sample is applied. This method is used to characterize the mechanical behaviour of a C68 high-carbon steel at temperatures up to 720◦C. Stress-strain curves are given from room temperature up to 720◦C at strain rates ranging from 1e−3 /s to 4 × 1e2 /s.
