Al-Zn-Mg-Cu aluminum alloys have the advantages of high specific strength, easy processing, and toughness, showing great potential application in aerospace field. However, ultra-high strength usually contain coarse microstructures, micro-segregation, casting defects that seriously deteriorate mechanical properties. Here, we report a high-strength alloy (Al-10.5Zn-2.0Mg-1.2Cu-0.12Zr-0.1Er) prepa...

Being a biocompatible metal with similar mechanical properties as bones, magnesium bears both biodegradability suitable for bone substitution and chemical reactivity detrimental in bio-ambiences. To benefit its biomaterial applications, we developed Mg-2.0Zn-0.5Zr-3.0Gd (wt%) alloy through hot extrusion and tailored its biodegradability by just varying the extrusion temperatures during alloy pr...
