| 摘 要： | 研究了在热等静压低压工艺参数下,T15粉末高速钢组织中析出粗大碳化物的现象,粗大碳化物使材料性能大大降低,并且发现很难通过后续的锻造和热处理手段加以消除,因而提出:合理选择粉末高速钢致密化工艺参数是十分必要的。

| Abstract: | Under the low pressure of hot isostatic pressing (HIP),coarse carbide appeared in the microstructure of powder metallurgy high speed steel (PM HSS) T15 which brought down material properties enormously.The measures that increasing forging ratio and time of heat treatment were difficult to eliminate coarse carbide.Sufficient pressure must be guaranteed to sinter PM T15 by HIP. |
