Abstract

Mg-alloys Mg97Y1.5Er0.5Ni1, Mg97Y1Er1Ni1 and Mg97Y0.5Er1.5Ni1 were fabricated by gravity casting method. Then the microstructure and tensile properties of the as-cast and solution-treated (520℃, 12 h) alloys were investigated by means of SEM with EDS, TEM and electronic universal testing machine. The results show that the as-cast alloys Mg97Y1.5Er0.5Ni1, Mg97Y1Er1Ni1 and Mg97-Y0.5Er1.5Ni1 are mainly composed of α-Mg matrix and 18R-LPSO phase. The grain size of α-Mg in the as-cast Mg97Y1Er1Ni1 alloy is the smallest and the volume fraction of LPSO phase is the highest among all the three alloys. Moreover, the as-cast Mg97Y1Er1Ni1 alloy presents the finest particles of LPSO phase and they also distribute much uniformly. Therefore, the as-cast Mg97Y1Er1Ni1 alloy shows the best tensile properties. After solid solution treatment at 520℃ for 12 h, the three alloys Mg97Y1.5-Er0.5Ni1, Mg97Y1Er1Ni1 and Mg97Y0.5Er1.5Ni1 all consist mainly of α-Mg matrix and 18R-LPSO phase. Inside the grains of the solution-treated Mg97Y1.5Er0.5Ni1 alloy, it is found that there are some stacking faults, which does not have a complete periodicity. The tensile properties of the three solution-treated alloys are all enhanced compared with those of the as-cast alloys.

Key words: metallic materials Mg-Y-Er-Ni alloy LPSO phase microstructure tensile property
