In this study , Zr65.7Cu15.6Ni11.7Al3.7Ti3.3 ( wt % ) MG structures were built on 304 stainless steel ( SS ) substrates by laser-foil-printing ( LFP ) additive manufacturing technology in which MG foils were laser welded layer-by-layer onto the SS substrate with a transition route , i.e. , SS → V → Ti → Zr → MG .
