Microstructure stability of Mg-Y alloys with Zn or Ag was studied. Microstructure and its development by heat treatment were studied and compared to physical and mechanical properties.
Solutes Zn and Ag are promising candidates in Mg alloys due to their antibacterial effects. The LPSO structure inherent to Mg alloys with small amount of Zn or Ag improves hardness only moderately.
Very long high temperatures thermal treatment is necessary to dissolve these structures. Addition of Nd depresses formation of the 18R LPSO particles.
