Abstract

The mechanical properties of a CuCr1Zr alloy were measured with the help of a Gleeble3500 machine at temperatures ranging from 250 °C to 1000 °C. Some tensile tests were alsoperformed at 20 °C. The measured data were first used to determine the thermal linearcoefficient at different temperatures. The measured curves were then simulated with anelasto-visco-plastic constitutive model assuming that the material behaviour wasisotropic. This law requires the knowledge of temperature dependent parameters that weredetermined by inverse method. This work represents a part of a PhD study on hot tearingsusceptibility during welding.
