Also, under the condition of stable temper temperature and with the temper time long, the trend get bigger of ferrite's recovering and recrystallion and the precipitation amount of carbide get more.

且在回火温度一定的条件下，随着回火时间的延长，铁素体回复再结晶的倾向增大，碳化物粒子析出量增多。

A new technology of extracting and recovering the titanyl sulfate solution was developed. Using different distribution coefficients of different metals in organic solvent, Ti4+ and the foreign metal ions were separated.

开发了对水解前钛液进行萃取-反萃处理操作的新工艺,利用不同金属离子在萃取剂中的分配系数不同,将杂质金属离子与钛离子分离开来。
