提高钢材的机械性能,主要是在钢中加入合金元素。苏联建筑工业部中央科学研究分所创造性地采用一种热处理方法,使低碳钢可以获得较高的强度,从而节约合金元素。现在我国冶金方面,正在研究新的钢种,以节约合金元素,因此低碳钢的热处理强化,值得推广,现介绍如下,仅供参考:热处理方法:与一般淬火方法相同,加热到 Ac_3+(80～50)℃,保温后立刻放入水中冷却。它所不同于一般淬火的地方,是低碳钢材处理后所获到的显微组
Improve the mechanical properties of steel, the main element is added to the steel alloy. The Central Institute for Scientific Research of the Soviet Ministry of Construction has creatively adopted a heat treatment method that allows low-carbon steels to achieve high strength and thus save alloying elements. Now China’s metallurgy, is studying new steel, in order to save alloying elements, so the heat treatment of low-carbon steel strengthening, it is worth promoting, are presented below, for reference only: Heat treatment method: As with the general quenching method, heated to Ac_3 (80 ~ 50) ℃, immediately after the insulation into the water cooling. It is different from the general quenching place, is obtained after the treatment of low-carbon steel microscopy group
