С целью установления возможных механизмов магнитопластического эффекта при старении бинарных медно-бериллиевых сплавов в постоянном магнитном поле выполнено экспериментальное исследование процессов агрегирования наноразмерных фазовых выделений в бериллиевой бронзе БрБ-2 методом микротвердости и остаточной намагниченности. Установлено, что постоянное магнитное поле существенным образом влияет на кинетику фазообразования в сплаве при старении, а именно, обнаруживается существенный «отрицательный» магнитопластический эффект. Предложены возможные качественные механизмы.
With the purpose of an establishment of possible mechanisms magneto-plastic effect at ageing binary cooper-beryllium alloys in a constant magnetic field the experimental research of processes of aggregation nanoscale phase precipitation in beryllium bronze BrB-2 is executed by methods of microhardness and residual magnetization. It is established, that the constant magnetic field significantly influences on kinetics phase formation in an alloy at ageing, namely, it is found out essential “negative” magneto-plastic effect. Possible qualitative mechanisms are offered.
