摘　　要：运用拉伸试验,金相组织分析等方法研究了合金元素钛含量对00Cr13Ni8Mo2TiNbAl马氏体时效不锈钢机械性能的影响。研究发现,钛含量增加,使钢中获得细小沉淀物的弥散分布,细化晶粒,增强时效硬化,从而提高该钢的抗拉强度。The effect of Ti content on mechanical properties of martensite stainless steel ooCr13Ni8Mo2 TiNbAl was studied by using the methods of tensile test and metallographic structure analysis. The results showed that as the content of Ti increasing ,fine precipitates distribute dipersely, grain fine and age - hardening enhanced in the steel, so tensile strength in this steel is improved.
