Paper Title:
Effects of Variable La/Ce Ratio on Microstructure and Mechanical Properties of Mg-5Al-0.3Mn-1RE Alloys
  Abstract

Effects of variable La/Ce ratio on microstructure and mechanical properties of Mg-5Al-0.3Mn-1RE alloys were investigated. The results indicated that pure La or pure Ce can improve ultimate strength and yield strength of AM50 effectively without obvious decrease of elongation, and the effect of La is better than that of Ce. However, addition of La and Ce together deteriorates the mechanical properties of AM50, and the valley of mechanical properties mostly appears on La:Ce= 1:1. The existence of coarse skeleton-like phase and less amount of Mg17Al12 phase is responsible for this.
