Abstract
The aim of this study was to investigate the effect of precipitates and cold working on the reheat cracking of STS 347 austenitic stainless steel. Three different heat treatments to form NbC and M23C6 precipitates were applied to the STS 347 austenitic stainless steel and 10% pre-strain was additionally introduced.....

DOI: https://doi.org/10.3365/KJMM.2017.55.7.470

Abstract
A feasibility study on microstructure design has been carried out to improve creep rupture life in alumina-forming austenitic (AFA) Fe-14Cr-20Ni-2.3Al stainless steel with and without 2 wt% W addition. After creep tests under 780 °C/80 MPa conditions, it was observed that internal cracks initiated primarily from grain boundaries in the..... More
