  • Webinar: Stress Relief Cracking in High Temperature Alloys


    Tuesday, December 17, 2019, 10:00 AM - 11:00 AM ET
    Many alloys used at high temperature exhibit stress relief cracking (SRC) during welding and/or post weld heat treatment (PWHT). This form of cracking typically occurs along the grain boundaries and results in a low ductility fracture. The problem is often associated with precipitation strengthening of matrix and localization of plastic deformation at grain boundaries to relax residual stresses from welding. In this work, we considered the effect of variations in PWHT temperature and cold working on the SRC susceptibility of a range of austenitic and ferritic alloys (Inconel 617, 740H, Haynes 230, 282, 347H, Grade 22 and 22V).
