与传统的金属材料相比 ,Ti Al金属间化合物密度低 ,熔点高 ,有较高的高温强度 ,有望用作新一代的结构材料。但 Ti Al金属间化合物一般较脆 ,加工性极差 ,在加工成品率和尺寸精度上也有很大问题。因此要实用还有待于新的低成本大批量生产加工方法的开发。金属粉末注射成型 (MIM) Compared with the traditional metal materials, TiAl intermetallic compounds with low density, high melting point, high temperature strength, is expected to be used as a new generation of structural materials. However, TiAl intermetallics are generally brittle and have poor processability, and also have significant problems in terms of process yield and dimensional accuracy. So to be practical yet to be the development of new low-cost high-volume production and processing methods. Metal Powder Injection Molding (MIM)
