| Краткий осмотр (реферат): | The development of novel alloys specifically designed for additive manufacturing (AM) is a key factor in using the full potential of AM. This study addresses the design of advanced high strength steels (AHSS) that take advantage of the processing conditions during AM by laser powder bed fusion (LPBF). The alloy screening was guided by computational alloy selection (combined CALPHAD, Scheil-Gulliver, and phase-field simulations) and by rapid processing using powder blends (X30Mn21 steel and Al). Increasing Al contents, ranging from 0 to 5.4 wt. %, promoted bcc-fcc solidification, and allowed for tailoring the stacking fault energy (SFE |
