Tensile Behavior of Semi-Solid C38 LTT Steel

Abstract:

The high temperature range for steel semi-solid state makes the experiments particularly challenging. While the response under shear or compression loadings was studied, few results concerned the response under tensile loading. In this paper, an experimental protocol was determined to characterize the uniaxial tensile response of the so-called C38 LTT steel with a Gleeble simulator. The specimen was heated by the Joule heating effect at around 10°C/s. The temperature was measured during the tests using an ultraviolet pyrometer. The variation in both ductility and strength of the material with temperature has been identified. The solidus-liquidus range was found to be shifted to lower temperatures.
