摘　　要：经择优取向校正、回归求解Ｋ值及抛弃平均处理，能显著减小无标Ｘ射线衍射相分析的误差。对合成样品及ＧＨ１６９合金中γ″及δ相变测定表明，其准确度与有标样法相当，相对误差≤６％。reatment with preferential orientation correction regressive solution and selective average,the error of phase analysis by X-ray diffraction without standard samples can be decreased obviously.It is shown from the results of synthetic samples and γ″→δtransformation in superalloy GH169 that the accuracy is equal to the method using standard samples,relative error less then 6%.

关 键 词：相分析 择优取向 耐热合金 无标X射线衍射
