Abstract

This paper presents high-temperature tensile testing. This method is used to characterize the mechanical behaviour of a high-carbon steel C68 at temperatures up to 720°C. Samples are heated by an induction system controlled with a pyrometer. A high-speed camera (500 fps) is used to determine the displacement field with a digital image correlation software. For such tests a specific marking procedure of the sample is applied. Stress-strain curves are given from room temperature up to 720°C at strain rates ranging from 10-3/s to 10-1/s. Elastic parameters of the material are measured at room temperature using cyclic tests. Bridgman’s method is used to determine the equivalent stress-plastic strain curve during the necking phase.
