Method for manufacturing vanadium carbide powder added tool steel powder by milling process, and method for manufacturing parts therewith |
摘要 |
A tool steel powder added with a vanadium carbide powder by a milling process, and a method for manufacturing parts therewith are disclosed. Particularly, a method for adding a vanadium carbide (VC) powder to a tool steel powder by a ball milling or an attrition milling, and a method for manufacturing a part by using the milled tool steel powder are disclosed. The method for manufacturing a vanadium carbide added tool steel powder and for manufacturing parts using the powder, includes the steps of: mixing a tool steel powder with vanadium carbide powder in an amount of 5 DIFFERENCE 15 wt %; ball-milling the mixture powder under wet atmosphere; carrying out an annealing in a vacuum; carrying out a cold die compaction or cold isostatic pressing to near net dimension and carrying out a vacuum sintering and then a hot isotropic pressing without canning.
