不同晶粒细化剂对铝镁合金线丝性能的影响

Effect of Different Grain Refining Agent on Properties of Aluminum Magnesium Alloy Wire

晶粒细化是提高铝镁合金铸件性能的重要途径,是铝镁合金线丝超强超细化的最有效方法和途径。文章研究总结了近年开发的Al-Ti-C-B是一种高效、长效且无毒化现象的细化剂,同时,鉴于稀土本身具有非常独特的优良特性,探讨并研究采用含有稀土的Al-Ti-C-RE丝以及Al-Ti-C-B-RE丝等多元中间合金晶粒细化剂将是今后一段时期铝镁合金线丝晶粒细化所采取的发展方向。

Grain refinement is an important way to improve the performance of the Al-Mg alloy castings and the most effective way to make super refined Al-Mg alloy wires. In recent years, the new developed Al-Ti-C-B is an effective grain refiner without the ＂ Poisoning＂ phenomenon. Due to the excellent properties of rare earth, Al-Ti-C-RE and Al-Ti-C-B-RE multiple intermediate alloy grain refining agents will be the future direction.
