摘　　要：采用真空渗流技术生产了泡沫Mg合金,深入地探究了工艺安全问题。分析了真空渗流时Mg合金发生燃烧与爆炸的原因,并给出了有效的解决方案。实验结果表明:采用金属铸型,合理控制金属液浇注温度与铸型预热温度可有效防止镁液燃烧;严格控制渗流过程中的水分与氧气可防止镁液爆炸。The foam magnesium alloy was produced by using vacuum flow technology. The process security problems were deeply explored. The reasons of burning and exploding for magnesium alloy were analyzed. Some effective solutions were gotten. The experimental results show that using metal mold and reasonable control of liquid metal pouring temperature and mould preheating temperature can effectively prevent the magnesium liquid combustion; strict control of water and oxygen in the seepage process can prevent the liquid magnesium explosion.

关 键 词：泡沫镁合金 真空渗流 燃烧 爆炸
