【摘要】：采用X射线衍射和透射电镜研究了V对Fe-Mn-Si合金不同变形条件下的马氏体相变特性的影响。研究表明:相同变形条件下,Fe-17Mn-5Si-2Cr-2Ni-1V合金中ε马氏体含量比Fe-17Mn-5Si-10Cr-5Ni合金的要多,且ε马氏体量的变化速率远低于Fe-17Mn-5Si-10Cr-5Ni合金。Fe-17Mn-5Si-10Cr-5Ni和Fe-17Mn-5Si-2Cr-2Ni-1V合金的应力松弛率均随停载时间的增加而增大,且Fe-17Mn-5Si-2Cr-2Ni-1V合金的松弛率大大低于Fe-17Mn-5Si-10Cr-5Ni合金。
[Abstract]:The effect of V on the martensite transformation of Fe-Mn-Si alloy under different deformation conditions was studied by means of X-ray diffraction and transmission electron microscope. The results show that the content of 蔚 martensite in Fe-17Mn-5Si-2Cr-2Ni-1V alloy is higher than that of Fe-17Mn-5Si-10Cr-5Ni alloy under the same deformation condition, and the change rate of 蔚 martensite content is much lower than that of Fe-17Mn-5Si-10Cr-5Ni alloy. Fe-17Mn-5Si-10Cr-5Ni and Fe-17Mn-5Si-2Cr-2Ni-1V alloy increase with the increase of stopping time. The relaxation rate of Fe-17Mn-5Si-2Cr-2Ni-1V alloy is much lower than that of Fe-17Mn-5Si-10Cr-5Ni alloy.
