摘 要：用快速凝固粉末冶金法制备完全致密的含Ti的Nb3Al-Nb固溶体两相合金，和铸锭法相比较， 所制合金的组织显著细化， 屈服强度显著提高。 通过Nb3Al与塑性相Nb固溶体的复合， 合金的低温脆性较Nb3Al明显减小。
Abstract: Nb3Al-Nb solid solution two-phase alloy doped with Ti is fabricated by rapid solidification powder metallurgy technology. The results show that the dense material with no porosity is obtained, and compared with ordinary solidification process, the microstructure of the alloy fabricated by rapid solidification process is extremely fine and the yield strength is considerably increased. By means of the compositing with ductile phase, the low temperature brittleness of the alloy is evidently decreased.
