Amorphous/crystalline Zn₆₀Zr₄₀ alloys lattice structures with improved mechanical properties fabricated by mechanical alloying and selective laser melting

In the present study, mechanical alloying (MA) was employed for synthesising non-equilibrium Zn60Zr40 amorphous powders, and then consolidated into amorphous/crystalline alloys using selective laser melting (SLM). The results showed that MA process destabilised atomic periodicity of Zn Zr powders induced crystalline-to-amorphous transformation due to size mismatch negative heat mixing. Moreover, amorphisation trend as-milled intensified with increasing milling time attained almost fully structure after 30 h milling. During SLM, ultra-high cooling rate restricted long-range diffusion enabled successful survival phase, leading alloys. exhibited a maximum compressive yield strength microhardness 160.9 ± 9.1 MPa 3.73 0.8 GPa, respectively. These findings demonstrated developed MA-SLM might be promising strategy preparation superior properties.
