Regulation mechanism of heat input on in situ tempering and precipitation behavior of wire arc additively manufactured 1,600 MPa low-alloy ultra-high-strength steel
With surging demand for lightweight, high-strength metal components in high-end equipment and large-scale engineering structures, additive manufacturing of low-alloy ultra-high-strength steel (LUHSS) has become a hot research topic. Wire arc additive manufacturing (WAAM) shows remarkable potential for fabricating large...
