抄録
The microstructure and mechanical properties of hot extruded Mg-Al-Zn-Ca alloys with different Lanthanum additions were investigated. Both rapidly solidified powders, produced via Spinning Water Atomization Process, and cast billets were extruded at 573, 623 and 673 K to optimize the processing conditions for obtaining better mechanical response. Powders were consolidated to prepare the extrusion billets using both cold compaction and Spark Plasma Sintering at 473, 573 and 623 K. The tensile properties of the extruded alloys were then evaluated and correlated to the observed microstructure. The results show that the use of rapidly solidified Mg-Al-Zn-Ca powder with La additions could lead to effective grain refinement, which in turn resulted in the improved mechanical response, especially compared to the extruded conventional cast material. The La content of 1.5% has shown superior tensile properties compared to that of 1.3%, and to other Mg alloys like AMX602, especially the elongation, as shown in Fig. 1. This may help extend the applications of Mg alloys to higher load carrying parts while maintaining the excellent advantage of light weight parts.

The microstructure and mechanical properties of hot extruded Mg-Al-Zn-Ca alloys with different Lanthanum additions were investigated. Both rapidly solidified powders, produced via Spinning Water Atomization Process, and cast billets were extruded at 573, 623 and 673 K to optimize the processing conditions for obtaining better mechanical response. Powders were consolidated to prepare the extrusion billets using both cold compaction and Spark Plasma Sintering at 473, 573 and 623 K. The tensile properties of the extruded alloys were then evaluated and correlated to the observed microstructure. The results show that the use of rapidly solidified Mg-Al-Zn-Ca powder with La additions could lead to effective grain refinement, which in turn resulted in the improved mechanical response, especially compared to the extruded conventional cast material. The La content of 1.5% has shown superior tensile properties compared to that of 1.3%, and to other Mg alloys like AMX602, especially the elongation, as shown in Fig. 1. This may help extend the applications of Mg alloys to higher load carrying parts while maintaining the excellent advantage of light weight parts.
