Abstract

The effects of Al content on the microstructure and fracture behavior of as-cast Mg-3Nd-1Y alloy were presented. The grain size, distribution and morphology of the secondary phase particles are closely related to the mechanical properties. As the content of Al increases, the secondary phases evolve from the β phase to small acicular Al11Nd3 and Al2RE particles, the distribution of the acicular Al11Nd3 phase becomes more uniform, and the amount and the size of Al2RE particles increase. The eutectic β phases and large Al2RE particles show a large cracking tendency. Because of the better interfacial bonding ability with the α-Mg matrix, cracking of the small Al2RE particles and Al11Nd3 phases is relatively lag. Therefore, rare earth compounds of small sizes can effectively prevent crack propagation. When 2 wt.% Al is added, fine grain size, fine intermetallic compounds and excellent mechanical properties can be obtained.
