Computational modelling for specific heat and thermal conductivity of austenitic stainless steels alloys at solid phase

Abstract

This work studied the special effects of the temperature on a number of austenitic stainless steels that are AISI 316, 316L, 304, and 304L Alloys at a solid phase. JMATPRO®, a computer program for modeling of material properties was used to simulate these alloys. The validity of the mathematical model is established by comparing the simulation outcomes with the parallel experimental results. The thermal conductivity and the specific heat of solid-phase fundamentally change with temperature. Calculated specific heat capacity at room temperature agrees very well with Dulong-Petit prediction, but is significantly smaller than those in the literature. It is brought into being that the thermal conductivity and the specific heat basically increase with temperature increases. Generally, the simulation results offered in this study are found to be in good agreement with the experimental results. Thus, the validity and applicability of the JMATPRO® model are established.
