Abstract Formulae derived for X-ray quantitative phase analysis without any standardin the case of specimens with identical texture have been shown to be in completeagreement with those derived by Zevin for randomly oriented specimens. Thus,when it is practicable by some ways (for example, by certain heat treatments) tochange the composition of the alloy phases without altering the texture of thespecimen, the method of quantitative phase analysis for such a textured specimencan be taken as identical with that for randomly oriented specimens. In cases where the absorption coefficients of the phases in a specimen happento be large, corrections for microabsorption are necessary and such corrections aregiven in the present work. The method mentioned above has been applied to a cold-rolled Fe-25%Mnalloy as well as to certain compacting specimens of Mo-Cu powders with satisfac-tory results.
