Fe-Zn supersaturated solid solution prepared by mechanical alloying and laser sintering to accelerate degradation

The slow degration of iron limits its bone implant application. The solid solution of Zn in Fe is expected to accelerate the degradation. In this work, mechanical alloying (MA) was used to prepare Fe-Zn powder with supersaturated solid solution. MA significantly decreased the lamellar spacing between particles, thus reducing the diffusion distance of solution atoms. Moreover, it caused a number of crystalline defects, which further promoted the...
