阻燃镁合金研究现状

Current Research on Ignition-proof Magnesium Alloys

详细介绍了含Ca、Be和RE等元素的阻燃镁合金研究现状,并指出了阻燃镁合金研究中存在的问题及未来的发展趋势。最终得出结论:加入Ca或Be元素会显著提高镁合金起燃温度,但过量的Ca和Be会严重恶化合金力学性能,而RE元素的少量加入不但能够提高合金起燃温度,而且RE对合金的力学性能会起到有益作用,因而其是未来阻燃镁合金的发展方向。

The current status of study on ignition-proof magnesium alloys containing Ca, Be and RE is described in detailed, the existing problems and the development tendency are also pointed out. Finally the conclusion is Ca or Be can improve the ignition temperature of magnesium alloys significantly, however, excessive Ca or Be will deteriorate the mechanical properties of alloys seriously. By adding a small amount of RE elements can simultaneously improve the alloy ignition temperature and the mechanical properties, so it is the future development trend of the ignition-proof magnesium alloy.
