一、前言纯金属钛中的氮以氮化物或固溶态存在。由于氮化钛非常稳定,所以在分析时若出现偏低的结果,则往往归咎于氮化钛难以分解,而固溶态的氮是否完全释出则注意较少。本文介绍利用悬浮熔融法研究在含有不同碳浓度的镍浴存在下纯钛中氮的释放状况,了解其中氮——化合氮和固溶氮——的释放过程,从而得出正确的分析方案。

I. INTRODUCTION Nitrogen in pure titanium metal exists as a nitride or solid solution. Since titanium nitride is very stable, it is often attributed to titanium nitride that is less likely to decompose when results of analyzes are low, while less attention is paid to whether the solid solution of nitrogen is completely released. In this paper, the release of nitrogen in pure titanium in the presence of nickel baths with different carbon concentrations and the release process of nitrogen-nitrogen and nitrogen-dissolved nitrogen in suspension are studied by suspension melting method, and the correct analysis scheme is obtained.
