近十多年来,用定向凝固工艺来制造涡轮叶片,已得到发动机设计者和冶金材料工作者的充分肯定,越来越多的发动机应用了定向凝固涡轮叶片和导向叶片,可以说定向凝固是继真空熔炼——精密铸造后的又一个成功。
For more than a decade, the use of directional solidification process to manufacture turbine blades has been fully affirmed by engine designers and metallurgical workers. More and more engines employ directional solidification turbine blades and guide vanes. It can be said that the directional solidification is Following vacuum melting - another success after precision casting.
