根据钢铁材料的微合金化原理和强韧化原理,对广泛使用的含钛渗碳钢的钛含量进行了理论计算分析和优化设计,结果表明,适当降低钛含量,不影响其在渗碳过程中阻止奥氏体晶粒长大的作用,但可有效地减少或消除含钛渗碳钢中的液析氮化钛,从而提高钢材的力学性能。

According to the microalloying and strengthening and toughening principles of steel, a theoretical calculation method and optimum alloying design to determine titanium content in carbonizing steel were proposed. The theoretical calculation and the experimental results showed that decreasing rationally the titanium content in carbonizing steel can effectively decrease or avoid the liquid precipitation of titanium nitride so as to improve the mechanical properties especially the contact fatigue property of the steel, while the function of controlling austenite grain size during carbonization is not effected.
