定向凝固镁合金组织形貌及力学性能研究进展
Research Progress on Microstructure and Mechanical Properties of Directionally Solidified Magnesium Alloys
摘要
Abstract
The crystal orientation and microstructure of magnesium alloys can be adjusted by directional solidification,which can improve mechanical properties of Mg alloys.At present,the research on directional solidification of magnesium alloys is far from enough.In this paper,the microstructure and cell/dendrite transition in directionally solidified Mg alloys was summarized,and the correlation between the growth orientation of the primary dendrite arm and mechanical properties of alloys was discussed.Moreover,the LPSO phase and the corrosion resistance of directionally solidified Mg alloys were summarized,and the research on numerical simulation of directional solidification process was reviewed.On this basis,the research directions in directional solidification of Mg alloys were proposed.关键词
