摘要
通过查阅大量的文献,分别从各种钢种的分析方法、加工工艺、合金化元素和不同组织对钢屈强强度、抗拉强度、屈强比、塑性、韧性和耐腐蚀性等方面的影响,特别是钢的耐腐蚀性能做出归纳。结果表明,钢的两大研究路线就是热处理和合金化,比如通过轧制、增大冷却风速、添加微量的稀土元素或是添加多元合金元素等,减小晶粒尺寸,改变珠光体片层结构,细化了片层间距,进而改变金相组织,改善了钢的屈强强度、塑性、韧性和耐腐蚀等性能。鉴于此,希望能帮助到更多的学者研究出更具成熟的工业化钢种,对世界工业化的发展、科技的发展、人类社会的进步有着重要意义。
By consulting a large number of literatures,the effects of the analysis methods,processing techniques,alloying elements and different structures of various steel types on yield strength,tensile strength,yield ratio,plasticity,toughness and corrosion resistance have been summarized and studied,especially the corrosion resistance of steel.It is concluded that the two main research routes of steel are heat treatment and alloying,such as reducing grain size,changing pearlite lamellar structure,refining lamellar spacing,changing metallographic structure,and improving yield strength,plasticity,toughness&corrosion resistance of steel by rolling,increasing cooling wind speed and adding trace rare earth elements or adding multi-element alloying elements.In view of this,it is hope to help more scholars to study more mature industrialized steel types,which has epoch-making significance for the development of world industrialization,the development of science and technology,and the progress of human society.
