Description

Features of the metastable phase states in Ti3Al+TiAl alloy, doped by niobium (2 at. %), are studied under heat treatment and ion irradiation. It is found that the disordered α phase with the face-centered cubic lattice is produced in the alloy during quenching from 1300 deg C and after ion irradiation (Ti+, 60 keV). It is shown that the structural transformations, stimulated by irradiation, depend on the initial state of the alloy and on the morphology of the phase components

Abstract (Russian)

Изучены особенности формирования метастабильных фазовых состояний в сплаве Ti3Al+TiAl, легированном ниобием (2 ат. %), при термическом воздействии и ионном облучении. Обнаружено, что при закалке от 1300 град С и после ионного облучения (Ti+, 60 кэВ) в сплаве образуется разупорядоченная α-фаза с ГПУ-решеткой. Показано, что структурные превращения, стимулированные облучением, зависят от исходного состояния сплава и от морфологии фазовых составляющих
