چکیده
Abstract In this study, the fatigue performance of butt-welded austenitic stainless-steel joints is investigated by test, nominal-stress method and peak-stress method. Welding profiles misalignment were analyzed, residual stresses measured, tests conducted. The experimental data are regressed to stress range vs. life-to-failure (S–N) curve nominal method, factor affected dispersion analyzed using following conclusion can be drawn: (1) strength 155 MPa in which higher than that structural steel (80 MPa) international design standards. (2) influence welding distortion accurately estimated combing reference S-N magnification formulae from

Sensitization Behavior of Gnaw Austenitic Stainless Steel Joints
The present work has been carried out to study the sensitization behavior of AISI 304L austenitic stainless steel weld, fabricated using GTAW (gas tungsten arc welding process). This weld was subjected to post weld thermal aging (PWTA) treatments lying in the sensitization range, viz. 700 ?C for 30 minutes, 500 minutes and 1000 minutes for studying the influence of carbide precipitation on thei...
متن کاملFatigue behavior of Austenitic Type 316L Stainless Steel
The aim of this work is to determine the fatigue life of 316L stainless steel. The mechanisms of fatigue of 316L stainless steels were investigated and discussed. The fatigue tests were carried out at constant-amplitude cyclic loading with load ratio R=0.1. Scanning Electron Microscope (SEM) is then used to examine the fracture surface. The results show that the fatigue limit of 316L stainless ...

متن کاملMechanical Properties of Austenitic Stainless Steel Made by Additive Manufacturing
Using uniaxial tensile and hardness testing, we evaluated the variability and anisotropy of the mechanical properties of an austenitic stainless steel, UNS S17400, manufactured by an additive process, selective laser melting. Like wrought materials, the mechanical properties depend on the orientation introduced by the processing. The recommended stress-relief heat treatment increases the tensil...
