俄罗斯科学院冶金和材料学研究所的专家最近用氮元素替换了钢中的碳元素 ,开发出了含氮量较高的新型钢材。据俄《消息报》日前报道 ,冶金和材料学研究所的专家在熔炼钢材时 ,用氮替换了钢中的碳。为使氮高效融入钢 ,科研人员向钢水中加入了含钼、钒、铌、铬、镍、锰等元素的物 Experts at the Institute of Metallurgy and Materials Science of the Russian Academy of Sciences recently replaced the carbon in steel with nitrogen and developed new types of steel with higher nitrogen contents. According to the Russian “Izvesto” recently reported that experts at the Institute of Metallurgy and Materials Science in the smelting of steel, with nitrogen to replace the carbon in the steel. In order to effectively incorporate nitrogen into steel, researchers added to the molten steel an article containing elements such as molybdenum, vanadium, niobium, chromium, nickel and manganese
