摘要/Abstract

摘要： 镁合金以其质量轻、比强度高、比刚度高、减震性好和易回收等优点被称为“21 世纪的一种绿色工程材料”，广泛应用于航空、航天、汽车和电子等行业。在汽车工业，采用镁合金替代钢或铝合金是汽车轻量化的有效途径之一，可以降低汽车燃油消耗和减少气体排放。高压铸造是镁合金成形的主要成形工艺，通过模拟仿真及实验研究提高镁合金压铸件质量及开发高真空压铸等高性能成形工艺是镁合金发展的重要方向。该文介绍了作者在镁合金压铸工艺试验研究、镁合金真空压铸技术开发、镁合金压铸工艺过程数值模拟及优化等方面的研究进展。

Abstract: Magnesium alloy is widely used in aerospace, automobile, and electronic industries and is referred to as the most promising green engineering material for the 21 century due to its lightweight, high specific strength and stiffness, good dumping performance and recyclability. Using magnesium alloy instead of steel or aluminum alloy in automobile industry is one of the effective ways to realize light weighting of automobiles to reduce fuel consumption and exhaust gas emission. High-pressure die casting process is the dominant manufacturing process for magnesium structural applications. The experimental study and modeling and simulation on high-pressure die casting process of magnesium alloys as well as development of vacuum die casting technology are important research directions for magnesium alloys. This paper highlights the research progress in experimental study on magnesium die casting process, development of vacuum die casting technology for magnesium alloys, modeling and simulation technologies for high pressure die casting process and their applications for process optimization.

Key words: automobile industry, magnesium alloy, high-pressure die casting, modeling and simulation
