The ternary alloys Ti Zr Co/ Fe is prepared by vaccum arc smelting and suction casting. 采用真空电弧炉熔炼及吸铸方法制备TiZrCo/Fe三元准晶合金系样品,对吸铸前后样品中存在的相进行了比较。
Abstract The shrinkage porosity functions used in the solidification process were reviewed in this paper. By using vaccum investment casting of IN 738 plate casting, the applicability of Niyama function G/ R 1/ 2 to the Ni based alloy has been proved. 本文对凝固过程中采用的缩孔缩松判据函数进行了评述,并结合真空精密铸造IN738合金板类铸件,验证了Niyama判据函数G/R1/2在镍基合金铸件中的应用。
