80年代低合金高强度钢中出现了一颗引人注目的新星,这就是铁素体加马氏体双相钢。这种产品强度高,塑性好,容易成型,受到人们的极大重视,发展很快。国际上冶金专家们一致把这种钢的出现看成是低合金高强度钢发展中的一个重要突破,标志着低合金高强钢的发展进入了一个新阶段。本文简要地介绍一下这种钢的发展概况,生产及应用现状,并就双相钢发展中存在的问题和未来的发展趋势,谈谈个人的看法。
In the 1980s, a striking star appeared in low-alloy high-strength steels, which is ferritic plus martensite duplex steel. This product is high strength, good plasticity, easy to shape, great attention by people, the rapid development. International metallurgical experts unanimously consider the appearance of this kind of steel as an important breakthrough in the development of low-alloy high-strength steel, marking that the development of low-alloy high-strength steel has entered a new stage. This article briefly introduces the development of this steel overview, production and application of the status quo, and the development of dual-phase steel problems and future trends, to talk about personal views.
