Abstract

チタン中の微量鉄,マンガンをけい光X線分析で定量する方法について検討した.供試料にはボタンインゴットと鍛造材とを用意し, 4分析所の共同実験という形で測定を行ない,検量線の作成,日内日間誤差のは握,所内所間誤差の算出,定量下限の推定,試料履歴差の影響などについて調べた.<BR>この結果,鉄含有率0.005~0.329%,マンガン含有率0.001~0.075%に対してそれぞれ0.003%以下, 0.0007%以下の精度(標準偏差)で分析可能であることがわかった.これらは標準化学分析法の精度と比較してまさるとも劣らないもので,微量成分に対してもけい光X線分析がじゅうぶん実用されうることを実証した.<BR>マンガンスペクトル線に対するクロムの影響,定量下限,試料履歴の差などについても考察した.

Parallel examinations were done on the fluorescent X-ray spectrometric determination of iron and manganese in button ingots and forged blocks of titanium metal to know the effect of metallurgical history on X-ray measurement, the limit of detection and the range of inner- and inter-laboratory errors. By using the working curves established, the standard deviations of the analytical values were 0.003% and 0.0007%, respectively, for 0.0050.329% of iron and 0.0010.075% of manganese. The lower limits of detectionof iron and manganese were, respectively, 0.0026% and 0.0007%. The precision and accuracy of the result were higher than, or at least comparable to, those of the conventional chemical analysis. Discussions were given on the influence of Cr on X-ray intensities of MnK<SUB>α</SUB> line and also on the effect of metallurgical history of the specimens.
