Electropulse-induced heating has attracted attention due to its high energy efficiency. However, the process gives rise to a nonlinear temperature variation, which is difficult to predict using a traditional physics model. As an alternative, this study employed machine-learning technology to predict such temperature variation for the first time. Mg alloy..... More

Enhanced Resistance to Delayed Cracking in Deep-drawn Lean Duplex Stainless Steel: the Role of Residual Stress
Seok Hwan Jung, Taekyung Lee, Seok Weon Song, Young Jin Kwon, Hyung-Gu Kang, Dongchul Chae, Chong Soo Lee
Korean J. Met. Mater. 2017;55(8):544-549.   Published online 2017 Aug 1
DOI: https://doi.org/10.3365/KJMM.2017.55.8.544

The delayed cracking behavior of deep-drawn lean duplex stainless steel (LDSS) was investigated, and compared with that of conventional metastable austenitic stainless steels (MASS). Hydrogen charging was performed by electrochemical method, and the hydrogen-charged specimens were subjected to the slow-strain-rate test. Fractures occurred along the phase boundaries in the LDSS,..... More
