氮在金属中主要是以化合物状态存在,在晶格内成为固溶体。金属材料中含氮过高,会降低金属的强度、塑性,不但给加工工艺带来困难,而且直接影响使用性能,因此准确及时地分析金属中氮含量,对于金属的冶炼,加工是十分重要的。一般氮的分析方法,有化学法、 Nitrogen is mainly present in the form of a compound in the metal and becomes a solid solution in the crystal lattice. Nitrogen in metal materials is too high, will reduce the strength of the metal, plastic, not only to the processing difficulties, but also directly affect the performance, so accurate and timely analysis of metal nitrogen content, for the metal smelting and processing is very important . General analysis of nitrogen, a chemical method,
