| 摘 要： | 用TEM-SEM、X射线及图象分析法研究了Fe-W(Mo)-Co(Ni)系时效硬化工具钢的相组成和组织。探讨了合金的时效硬化机制,确认时效初期发生无位垒脱溶—调幅分解,形成具有周期构造的组织,它的成长速度非常缓慢,这是本系合金时效硬化迅速和过时效软化迟缓的原因。

| Abstract: | The phase constituent and structure of a Fe-W(Mo)-Co(Ni) age hardening tool steel were investigated by TEM-SEM, X-ray and image analysis. The mechanizm of age hardening indicated that the non-barrier precipitation-spinodal decomposition happened at the initial stage of age hardening to form a period structure, the growth of this structure was very slow, and it caused the fast hardening and slow softening in the aging process. |

| Keywords: | tool steel spinodal decomposition age hardening |
