本文综合比较了在中碳和低碳结构钢中改善其强韧特性达到超高强度钢水平的工艺措施和合金设计准则.系统地采用正交设计和回归分析方法,并运用微处理技术研究了Si-Mn-Cr-Ni-Mo-V系列低碳马氏体型超高强度钢的成分与性能的关系,得出了反应这一定量关系的回归方程.明确了碳和合金元素对这类钢强韧特性的主要贡献,从而得出该系列钢种的最优化成份范围.文中就典型成份钢种的强韧特性和组织结构关系,分析讨论了该系列钢种强韧化的本质,指出了发展低碳马氏体型超高强度钢的可能性和优越性.
In this paper, a comprehensive comparison of the process measures and alloy design criteria for improving the toughness characteristics of medium- and low-carbon structural steels to achieve ultra-high strength steels has been carried out.Orthogonal design and regression analysis methods are systematically used and the effects of micro- Si-Mn-Cr-Ni-Mo-V series of low-carbon martensitic ultra-high strength steel composition and performance of the relationship between the reaction obtained the quantitative relationship between the regression equation clear carbon and alloying elements of this type of steel Toughness characteristics of the main contribution to arrive at the scope of the optimal composition of the series of steel grades.This article on the toughness characteristics of typical components of steel and organizational structure, analysis and discussion of the series of steel toughening essence, pointed out that Development of low-carbon martensitic ultra-high strength steel possibilities and advantages.
