Investigation of metallurgical mechanism governing the disorder/order transformation in high-silicon steels manufactured by L-PBF

Maria Rita Ridolfi, Giulia Stornelli, Bryan Ramiro Rodríguez-Vargas, Paolo Vescovo et autres

Laser-Powder-Bed-Fusion is a promising technology for manufacturing ferromagnetic components in High-Silicon steels to overcome the problem of intrinsic brittleness. To date, the mechanisms governing the formation of the ordered-brittle B2 and D0 3 phases, from the primary disordered-ductile A2 phase, are still …

Role of vanadium in welding of flat products in high strength low alloyed steels: microstructure and mechanical properties

Andrea Di Schino, Michelangelo Mortello, Bryan Ramiro Rodríguez-Vargas, Rolf Schmidt et autres

The use of High Strength Low-Alloy (HSLA) steels in structural applications requires detailed analysis of their microstructure to optimize the strength and toughness of welded joints. During multi-pass welding, thermal cycling generates a complex heat-affected zone (HAZ) with subregions containing brittle phases …
