低合金高强度钢自50年代就引起人们的重视,到了60至70年代随着微合金化技术的发展。低合金高强钢成为材料科学中较为活跃的研究领域。除了合理的成份设计和正确的冶炼方法以外,低合金高强钢的良好性能取决于材料自身的加工特性与相应的控制加工技术合理匹配。本文研究了用于汽车减重和节能的含磷低碳钢和双相钢的变形抗力。
Low-alloy high-strength steel has aroused people’s attention since the 1950s, with the development of micro-alloying technology from the 60s to the 70s. Low alloy high strength steel has become more active in the field of materials science research. In addition to reasonable compositional design and correct smelting methods, the good properties of low-alloy high-strength steel depend on the material’s own processing characteristics and the appropriate control processing technology to match reasonably. This article studies the deformation resistance of phosphorus-containing low-carbon steel and dual-phase steel for weight reduction and energy saving in automobiles.
