- 摘要:
- 综述了目前国内镁合金的几种晶粒细化方法,包括液态凝固过程的细化晶粒法,如异质形核法、快速冷却法、附加振动法、半固态成形晶粒细化法。固态成形过程的细化晶粒法,如具有代表性的等通道转角挤压法、高压扭转法、大应变轧制法。分析了镁合金晶粒细化研究的研究进展和存在的问题,为进一步开发绿色高效的镁合金晶粒细化技术提供一些思路。Several grain refining methods of magnesium alloys in China,including those of liquid solidification,such as heterogeneous nucleation,rapid cooling,additional vibration and semi-solid forming,and refinement of grain in solid state forming process,such as representative equal channel angle extrusion method,high pressure torsion method,large strain rolling method were reviewed.The research progress and existing problems of grain refinement of magnesium alloys were analyzed,which provided some ideas for further developing green and efficient grain refinement technology of magnesium alloys.
