that the prepared master alloy consisted of α-Al, TiAl3, TiC and Al3Y phases, and exhibited good grain-refining performance of AZ31 alloy. Morphology of α-Mg changed from coarse dendritic to fine equiaxed and the average grain size of α-Mg matrix reduced from the original 580 to 170 μm after adding 1.0 wt.% master alloy. The grain refining efficiency of Al-Ti-C-Y master alloy on AZ31 alloy was mainly......

, the corrosion current density is reduced by two orders of magnitude compared with that of uneroded Mg68Zn32 alloy. Key words: as-cast magnesium alloy; corrosion resistance; icosahedral quasicrystal; Mg-Zn... of Mg68Zn32 and Mg68Zn28Y4 were prepared from the master alloy Mg-25%Y (mass fraction), high purity Mg (99.9%, mass fraction) and Zn(99.9%, mass fraction) by melting in graphite crucibles in 3 kW electric......
