In the present work, low-current-density electropulsing was applied to study the recrystallization behavior of a hot-rolled TiBw/TA15 composite. To highlight the athermal effect of electropulsing, traditional heat treatment experiments on composite materials were conducted under the same conditions. Test results indicated that recrystallization behavior can be improved compared with that in traditional heat treatment. The potential mechanism by which electropulsing promotes recrystallization was investigated, and the influence of the reinforcement phase on recrystallization was discussed. This work will provide freedom for the composite's process design and microstructure control.
