- (1)
- The as-cast Al-10Ce-3Mg-xZn alloys consist of α-Al, a Chinese-script eutectic phase, and a bulk primary phase. The volume fraction of the Al11Ce3 phase in the alloy increases as the Zn content increases, and the majority of the Zn element is concentrated in the Al11Ce3 phase; when the Zn addition is increased to 5 wt.%, the regularly distributed acicular Al2CeZn2 phase is formed within the Al11Ce3 phase.
- (2)
- The alloy with 5 wt.% Zn exhibited a significant increase in microhardness, elastic modulus, and fracture toughness of the Al11Ce3 phase compared to the alloy without Zn addition; this indicates that the increase in the Zn content significantly enhances the second-phase strengthening effect of the alloy.
- (3)
- The addition of Zn can significantly enhance the hardness and mechanical properties of Al-10Ce-3Mg alloys through the combined effect of solid solution strengthening and second-phase strengthening. The UTS and YS of the Al-10Ce-3Mg alloy increase with increasing Zn content at room temperature, while the EL gradually decreases. The decrease in EL is due to the increase in the volume fraction of the Al11Ce3 phase as a source of fracture; the alloy with 5 wt.% Zn exhibits the highest UTS at all test temperatures, indicating that the alloy has superior heat resistance.
