MODE OF CONTROLLING QUALITY OF ARTICLES OUT OF HARD ALLOYS AFTER RADIATIONAL-THERMIC PROCESSING Russian patent published in 2007 - IPC G01N23/20 

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 (β) of two patterns of reflection from one aggregate crystallographic planes that is β₁ and β₂ and an angular positions of centers of the whole weight (θ) of selected lines that is θ₁ and θ₂, 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.
