摘要: The minor alloying element Zr in a Mg–6.2Zn–0.6Zr (ZK60) alloy causes the formation of fine Mg(Zn,Zr) precipitates at 350 °C which play critical role dynamic recrystallization during extrusion and hot rolling. When is artificially aged 160 °C, β 1 ′ -precipitate grows [0 0 0 1] direction from particles. structure exactly same as that , indicating partitioning occurs only elevated temperature due to sluggish diffusion Zr.
