METHOD OF DIAGNOSIS OF FIRST-ORDER PHASE TRANSITIONS IN SINGLE CRYSTALS

摘要

the invention u043eu0442u043du043eu0441u0438u0442u0441u00a0 to technical physics, namely research, and may find application in the detection of phase transitions (op) 1st kind in different x construction materials. to improve the accuracy of diagnosis u0438u0437u043eu0431u0440u0435u0442u0435u043du0438u00a0 u00a0u0432u043bu00a0u0435u0442u0441u00a0 1st kind. method u043eu0441u0443u0449u0435u0441u0442u0432u043bu00a0u0435u0442u0441u00a0 as follows. the researched model're injecting flow of accelerated ions of inert gas.the sample at a temperature above the temperature of the u043du0430u0445u043eu0434u0438u0442u0441u00a0. after the completion of irradiation (up to the specified area) the specimen cooled with simultaneous mass spectrometric recording speed, desorption of atoms eneicher u0442u043du044bu0445 gases. on a dramatic increase in the speed of judge the existence and the desorption temperature. 1 il.
