Abstract

The nuclear magnetic resonance (NMR) method is employed for the first time for quantitative analysis of dilute metallic alloys, thereby allowing the non-destructive determination of the concentration of foreign atoms present in a dissolved state in the metal matrix. Valuable information can be obtained on the real structure of given alloys by comparing the dissolved impurity content obtained by NMR measurements and total impurity content determined chemically. The method is based on the measurement of the NMR intensity as a function of dissolved foreign atoms, the NMR signal intensity being measured through the derivative signal amplitude (D) with log D expressed as a linear function of the foreign atom concentration.The slope of the curve depends on the nature of the foreign atom. Sample preparation, apparatus and procedure are described.
