MODE OF CONTROLLING QUALITY OF ARTICLES OUT OF HARD ALLOYS AFTER RADIATIONAL-THERMIC PROCESSING

FIELD: the invention may be used for controlling quality of articles out of hard alloys after radiational-thermic processing. ^ SUBSTANCE: the mode is in that the sample is impacted with x-ray radiation for registering its diffracting spectrum, definition of the concentrations of carbide phases - of monocarbide of tungsten WC and compound carbide (Ti,W)C- in a hard alloy of the composition WC-TiC-Co, definition of physical broadening (beta) of two patterns of reflection from one aggregate crystallographic planes that is beta1 and beta2 and an angular positions of centers of the whole weight (theta) of selected lines that is theta1 and theta2, control of quality of the articles after radiational-thermic processing, in defining the coefficient of resistance of articles out of hard alloys after radiational-thermic processing, conditions of counting the value of integral disordering of the carbide phases and disordering of monocarbide WC relatively to the given values. ^ EFFECT: estimation of quality and unique forecasting of the term of service of articles subjected to radiational-thermic processing and simplification of the mode. ^ 3 tbl
