a way to identify the boundaries u03b2 - grains in u0432u044bu0441u043eu043au043eu043bu0435u0433u0438u0440u043eu0432u0430u043du043du044bu0445 (various + u03b2) titanium alloys, comprising a high-speed heating, cooling in water, the additional heating, the subsequent refrigeration, cooking u043cu0438u043au0440u043eu0448u043bu0438u0444u0430 and subsequent chemical etching, and the fact that, in order to improve the accuracy and reduce the labour intensity of measured and the u03b2 - grainthe additional heating by 25 - 50 degrees c below the temperature of various + u03b2u2192u03b2 - making within 30 to 60 min and subsequent cooling by air.
