Effects of Aging Treatment on Laser-Welded Mg-Rare Earth Alloy NZ30K

Effects of Aging Treatment on Laser-Welded Mg-Rare Earth Alloy NZ30K

Magnesium-rare earth alloys have received extensive attention due to their attractive mechanical properties resulting from high density of precipitation. The precipitation sequence in laser-welded Mg-3Nd-0.2Zn-0.4Zr (NZ30K) alloy during aging treatment at 200°C and 225°C has been investigated using...
