探讨稀土在Al-Ti-B-Re中间合金中的作用

The effect of rare-earth on Al-Ti-B-Re inter midiate alloy

采用电解抛光和阳极复膜处理金相试样，对Ａｌ－Ｔｉ－Ｂ－Ｒｅ中间合金进行金相组织分析，并观测其细化处理的铸态铝及铝合金的晶粒大小和枝晶间距，同时分析了其在生产中的应用，探讨了稀土在Ａｌ－Ｔｉ－Ｂ－Ｒｅ中间合金中的作用。

Treating Samples by electrilylic polishing and anodes co ating, metallographic structure of Al-Ti-B-Re intermidiate alloy has been analyzed ,an d observated the crystal grains and distance of dentric crystals on minishment of crystal grain of Al-Ti-B-Re casting Al and its Al-alloy; then application on Al-Ti-B-Re alloy in indrodnction has been analyzed;the effect of rare-earth on Al-Ti-B-Re intermidinte a lloy has heen commentaried in the thesis.
