Pressure Influence on the Thermophysical Properties of 316L Austenitic Stainless Steels Manufactured By Powder Metallurgy Method

Abstract

Austenitic stainless steel that is used in the industrial areas such as automotive has high physical and mechanical properties. In this study; thermophysical properties of 316L austenitic stainless steel prepared by powder metallurgy method that is attracted for researchers due to obtain net or near shaped product and complex shaped materials, have been investigated. Austenitic stainless steels pressed on the 400 and 600MPa pressures and pressed austenitic stainless steel samples sintered at 1200 °C temperature for an hour under inert gas atmosphere. The thermophysical features o these sintered austenitic stainless steel were performed at temperature ranging from RT to 600 °C via heat flux type Differential Scanning Calorimeter (DSC). These properties supported by SEM images, EDS spectrums and OM (Optic microscope) images.
