| 摘 要： | 研究了含2%W和V的Fe-Cr-Mn合金经热时效处理和电子辐照条件下,溶质元素晶界偏聚和析出相的行为。实验结果表明:在含W、V合金中热时效引起Cr、Mn晶界贫化,它决定于富Cr碳化物M23C6中组元组成。辐照条件下,两种合金中Cr、Mn都发生晶界贫化,它决定于辐照产生空位浓度和空洞体胀量,辐照诱起晶界元素偏聚影响析出相成分。

| Abstract: | Behaviour of grain boundaries segregation and precipitate in Fc-Cr-Mn and Fe-Cr-Mn-W-V alloys were investigated during thermal againg and irradjation by electron beam.
Experiments show that Cr, Mn are depleted on grain boundaries during thermal aging in Fe-Cr-Mn-W-V alloy. It is depended on chemical composition of M23C6 type chromium-carbides. Cr and Mn in both alloys mentioned above are depleted on grain boundaries during irradiation. It is depended on concentration of radiation-induced cavity and void swelling. Radiation-induced segregation effects on chemical composition of precipitate M23C6 in both alloys. |
