1 论文所涉及的内容 (1)钢种:除传统的铁素体基体型用Nb、Ti、V等元素强化的钢种外,还有贝氏体型的、双相型的、无间隙原子钢和相变诱发塑性变型的钢种。铁素体型的钢种仍是主力军。 (2)工艺:在冶炼上采用钢包冶金、脱氧、去除夹杂物一并进行,活泼性添加剂,如钙,采用射入法或丝线馈给方式,保证稳定的回收率。 细化晶粒与控制脱溶相粒子的弥散度仍是强化F-P型HSLA钢的主要途径。细化
1 Papers involved (1) steel: In addition to the traditional ferrite matrix type with Nb, Ti, V and other elements of steel reinforced, there are bainitic, biphasic, gapless atomic steel And phase change induced plastic deformation of steel. Ferritic steel is still the main force. (2) Process: Ladle metallurgy, deoxidation, removal of inclusions in the smelting together, lively additives, such as calcium, using the injection method or wire feed, to ensure a stable recovery rate. The grain refinement and the control of the dispersion of the desolvated particles are still the main ways to strengthen the F-P HSLA steel. Refine
