内容記述 |
In this study，we systematically investigate on the influence of additional carbide stabilizer elements，M (M＝V, Ti or Nb) on the amount, morphology and distribution of crystallized M_7C_3 and/or MC type carbides in alloy tool steel (SKD11 of JISG4404) castings during solidification. The base chemical compositions of the steel castings，produced by the investment casting process are 1.5 mass％ C，12 mass％ Cr and 0.3 mass％ V. The castings were melted in a high frequency induction furnace and melts varying from 0.3 mass％ V to 5 mass％ V，from 0.5 mass％ Ti to4 mass％ Ti and from 0.5 mass％ Nb to 5 mass％ Nb were cast into an alumina mould 14 mm in thickness，heated to 1,373K. Microstructure of steel casting without addition of carbide stabilizer elements M consists of dendritic iron matrix and continuous plate-like eutectic (Fe，Cr)_7C_3 carbide. With increasing M cont.ent, crystallized carbide in the castings were found to change from (Fe，Cr)_7C_3 type to granular MC type，crystallizing randomly owing to stronger stabilization of the carbide of M than Cr. Therefore，( Fe，Cr)_7C_3 carbide is dispersed or separated by crystallization of MC type. The dispersing or separating situation is remarkable in the order to V ＜Nb＜Ti addition. From analytical results of distribution of elements by energy dispersive X-ray (EDX) analysis， and detection and identification of carbides by X-ray diffractometry，crystallized MC type carbides constitute VC, TiC or NbC type ones, corresponding to additional elements M of V, Ti or Nb |
