| 摘 要： | 通过萃取复形薄膜的方法,采用高分辨透射电镜和能量色散X射线光谱技术,研究了Nb-V-Ti和V-Ti微合金钢中,Nb、V、Ti的碳氮化物在不同温度和不同时间下保温时的回溶情况.结果表明,Nb-V-Ti微合金钢中较大的析出物是由少量的Nb、V和大量Ti一起在凝固过程中析出,形成复合的(Nb,V,Ti)(C,N)析出物.V-Ti微合金钢中,Ti的加入对于V的回溶具有拖曳作用.

| Abstract: | With the aid of extraction complex of C thin film,TEM and energy dispersion X-ray spectrum(EDX),the dissolve rule of Nb,V and Ti in Nb-V-Ti and V-Ti microalloyed steel was studied by isothermal holding at different temperatures and for different time.The results show that the large precipitate which is Ti-rich with a little Nb and V precipitate in solidification and form complex(Nb,V,Ti)(C,N) precipitate.The dissolution of V in V-Ti microalloyed steel is restrained by Ti. |
