摘要:
提高模量对扩大镁基材料的应用范围意义重大,高模量镁基材料的研究开发正受到国内外学者们的广泛关注和高度重视。本文综述了国内外高模量镁基材料的最新研究进展,阐述了工艺条件、合金化以及复合化对提高镁合金弹性模量的作用及效果,分析了弹性模量提升的内在机制,并介绍了高模量镁基材料的力学性能。通过合金化在镁合金中加入一定量的合金元素,和通过复合化在镁基体中添加陶瓷颗粒、晶须或纤维等各种增强体,能显著提高镁基材料的弹性模量。最后讨论了高模量镁基材料研究目前存在的主要问题,并对今后高模量镁基材料的发展趋势进行了展望。
Abstract:
It is of great importance to increase the modulus of magnesium matrix materials for enlarging its application. At present, the research and development of high-modulus magnesium matrix materials have received much attention all over the world, and consequently many researches have been carried out. In the paper, the latest research progress of high-modulus magnesium matrix materials are reviewed. The effect of process conditions, alloying and composited process on improving the elastic modulus of magnesium alloys are illustrated. The internal mechanism of elastic modulus improvement and mechanical property of magnesium matrix materials are analyzed and introduced respectively. A certain amount of alloying elements are added to the magnesium alloys by alloying process, and various reinforcements such as ceramic particles, whisker or fiber reinforcements are added to the magnesium matrix by composited process, in order to significantly increase the elastic modulus of magnesium matrix materials. Finally, the main problems existing in the study and the future research direction of high-modulus magnesium matrix materials are discussed and proposed respectively.
