铝-钛-碳合金中碳的分析方法研究与应用

Study and application on Method for Determination of Carbon in AlTiC Alloy

提出了一个测定难熔合金(AlTiC)中碳的新方法。采用HCl+HF加热分解样品,让碳游离出来,经石棉吸附碳并烘干后,按非水滴定法测定碳的含量,效果良好。

A new method for determination of carbon in refractory AlTiC alloy has been developed.In this method,the sample is heated in HCl+HF and the free carbon is separated.Then,the carbon is absorbed with asbestos and overdried,followed by nonaqueous titration to determinate its content.This method gives satisfactory results.
