| 摘 要： | 在"低碳Fe-W(Mo)-Co(Ni)合金研究(A)和(B)"的基础上研究了该合金的硬化特性及硬化机理。本系合金具有显著的时效硬化特性:在550℃进行时效处理5～10min,硬度就将上升20～30HRC。时效曲线上出现的二次硬化暗示在时效时有两种硬化机制在起作用。实验表明,在时效过程中Co-Ni合金发生马氏体向奥氏体的逆转变,而高钴合金则未发现这种情况。

| Abstract: | The paper researched hardening characteristics and mechanism of low carbon Fe-W （Mo）-Co （Ni） alloy on the basis of ＇ Study on Low-Carbon Fe-W （Mo） -Co （ Ni ） alloy （A） and （ B ） ＇ The series of alloy possesses significant age hardening characteristic for from 5 to 10 minutes aging at 550 ℃ will result in hardness increase from 20 to 30 HRC. Secondary hardening appeared on the aging curve implies that two kinds of hardening mechanism are functioning in aging process. Experiment result indicates that in the aging process reverse phase transformation from Martensite to Austenite occurs in Co-Ni alloy and such case was not found in high Cobalt alloy. |
