钛微合金化高强钢含Ti第二相的热力学计算

Thermodynamic Calculation of Ti-containing Second Phase in Ti Microalloyed High Strength Steel

利用热力学计算软件Thermo-Calc,对不同Ti含量和不同N含量的高Ti微合金化高强钢进行计算和分析,研究Ti、N元素对高Ti微合金化高强钢中含Ti第二相固溶析出的影响。结果表明,在一定条件下,减少N元素含量,增加Ti元素含量,使得Ti收得率最大,获得更多的有益相TiC,减少有害相TiN的含量。

Using thermodynamic Thermo-Calc software the calculation and analysis of high-Ti microalloyed high strength steel with different Ti content and different N content were carried out to study the effect of Ti and N elements on solid solution precipitation of Ti-containing second phase in high-Ti microalloyed high strength steel. The results show that under certain conditions,decreasing N content and increasing Ti content can improve Ti yield and obtain more beneficial phase TiC and reduce the volume fraction of harmful phase TiN.
