日本开发了一项用于制造钛引擎阀的粉末冶金(P/M)锻造技术。据报道,该技术可降低引擎阀的成本,还可使引擎的自重降低40％。 吸气阀采用Ti-6Al-4V材料,用粉末冶金锻造工艺制造。排气阀采用钛复合物—含有硼化物强化颗粒的新型粉末冶金钛合
Japan has developed a powder metallurgy (P / M) forging technology for making titanium engine valves. It is reported that this technology can reduce the cost of the engine valve, but also to reduce the engine’s weight by 40%. Suction valve with Ti-6Al-4V material, using powder metallurgy forging process. Exhaust valves use titanium compounds - a new powdered metallurgical titanium alloy with boride-reinforced particles
