A Study on the Effect of Test Temperatures on Tensile and Fracture Behavior of SS 316LN

CODEN: MPCACD

Abstract

In the present study, the influence of test temperatures in the range of 25°C–550°C on the deformation and fracture behavior of SS 316LN has been investigated. The tensile properties and fracture toughness (J1c) of SS 316LN have been evaluated in this temperature range. From tensile properties, strain energy density was estimated as a function of plastic strain and strain-hardening parameters. The fracture tests (J-R curves) are conducted in this temperature range to determine fracture toughness and tearing resistance. From the fracture tested specimens, fractographic studies were carried out to further understand crack initiation mechanisms. From the results of fracture toughness in the temperature range of 350°C–450°C, an attempt to understand the deformation mechanism was made based on an empirical equation.
