【摘要】Recently,TiAl+Nb alloys have attracted much attention aspotential high temperature (HT) structural materials because of their outstanding HT strength. Great progress has been gained in studies on phase diagram and oxidation resistance studies. Nb addition may provide the promise of engineering applications of TiAI based alloys containing high amounts of Nb.%论述了Nb-TiA1系金属间化合物在高温强度及抗氧化性方面已取得的进展。高熔点组元Nb提高了合金的熔点和有序温度,从而使合金的使用温度达到900°C以上。该体系合金显示出来的潜力具有代替Ni基合金的趋势。 【总页数】3页(15-17)
