从2001年2月12日~15日TMS轻金属学术会议传出的消息称：日本金属研究所已研制成功一种具有良好断裂韧性的粉末冶金钛基金属间化合物。该化合物主要为斜方晶系β相，基体的化学成分为Ti-22Al-27Nb，含量为6.5%TiB2颗粒作为增强物。通过粉末冶金工艺可以提高该钛基金属间化合物在
From February 12, 2001 to 15, TMS light metal conference came the news that Japan Institute of Metals has successfully developed a good fracture toughness of powder metallurgy titanium-based intermetallic compounds. The compound is mainly orthorhombic β phase, the matrix of the chemical composition of Ti-22Al-27Nb, content of 6.5% TiB2 particles as a reinforcement. The powder metallurgy process can improve the titanium-based intermetallic compounds
