LCF Comparison Study on Modified ASS with Conventional ASS in Longitudinal and Transverse Directions

The tensile deformation at a strain rate of 1 x 10-3 s-1 and low cycle fatigue test at a strain rate of 5×10-3 s-1 with a strain amplitude ranges from ±0.5% to ±0.7% were carried out on hot rolled annealed modified austenite stainless steel (ASS) at room temperature in longitudinal and transverse di...

Description
Summary:The tensile deformation at a strain rate of 1 x 10-3 s-1 and low cycle fatigue test at a strain rate of 5×10-3 s-1 with a strain amplitude ranges from ±0.5% to ±0.7% were carried out on hot rolled annealed modified austenite stainless steel (ASS) at room temperature in longitudinal and transverse directions. The tensile and fatigue life of modified austenite stainless steel were increased than the conventional ASS in both the directions. The microstructures and fractography of the tested specimens were analyzed by SEM to understand the deformation behaviour and the mode of fracture.
