摘要
镁合金作为一种新型的工程材料具有许多独特的优点,锆作为微量元素加入到镁合金中,可以细化合金的微观组织,显著提高材料的力学性能,减少夹杂,改善镁合金的抗腐蚀性能等。论述了锆元素对镁合金各项性能的作用机理、锆元素细化镁合金晶粒的机制,提出合金制备过程中的加锆方式应是含锆镁合金今后研究的重点。
As a new type of engineering material, magnesium alloy has many unique advantages. The addition of trace element Zr into magnesium alloy can refine the microstructure, enhance the mechanical properties significantly, reduce the inclusion and improve the corrosion resistance of magnesium alloys. The effect of zirconium element on various properties of magnesium alloys and the mechanism of the grain refinement were discussed. The adding Zr ways during preparing process should be the emphasis in the future.
