WebHere, a new strategy is demonstrated to achieve ductile BCC HfNbTiV, via decomposing the BCC arrangement (β phase) into a β(BCC 1) + β*(BCC 2) arrangement via spinodal decomposition, producing chemical composition modulations and, more importantly, elastic strain on a length scale of a few tens of nanometers. WebApr 14, 2024 · High-strength, low-alloy (HSLA) steel has attracted much attention in the manufacturing industry because of its good combination of high strength and toughness, low cost, and good formability. Wire and arc additive manufacturing (WAAM) technology can realize the rapid prototyping of HSLA steel parts. This study investigated a 26-layer …
