摘要:

利用10Ni和18Ni马氏体时效钢穆斯堡尔谱, 研究10Ni和18Ni两种马氏体合金钢的时效机理.  研究表明: 10Ni和18Ni马氏体时效钢存在富Fe\|Co区域和富Fe-Ni-Mo区域, 在时效初期, Mo原子的偏聚速度较快;  10Ni合金时效30 min后析出金属间化合物,  18Ni合金时效15 min后析出金属间化合物.  由超精细内磁场值变化可知, 随着时效时间的增加, Co原子作为与Fe原子最近邻的配位几率增加.

Abstract:

 Stages of ageing mechanism of 10Ni and 18Ni maraging steels were studied by means of Mssbauer spectroscopy of 10Ni and 18Ni maraging steels. The results show that  Fe\|Co\|rich and Fe-Ni-Mo-rich regions existed in the steels. Mo atom migrated rapidly at the initial stages of ageing. The paramagnetic intermetallic compounds were observed in the 10Ni maraging steel after ageing  for 30 min,  and  in the 18Ni maraging steel after ageing for  15 min. From the change in hyperfine field, the bond probability of Fe atom with the nearest Co atom increases with increasing the ageing time.

Key words: Mossbauer effect, 10Ni and 18Ni maraging steel, modulated structure, hyperfine field
