Abstract

Barium plumbate particle (BPOp)/2024Al was fabricated by ball milling and hot-pressing sintering. Nanosized Pb particles were formed from the in-situ reaction between BPOp and 2024Al matrix, and mainly distributed homogeneously inside grains. They have melting undercooling behavior due to the nanoscale effect. The hot extrusion deformation of the composite at different temperatures was performed to investigate the effect of Pb liquid phase on the deformation. The results show that the presence of the liquid reduces deformation resistance by decreasing dislocation pile-ups. In addition, the liquid acted as lubricant to accommodate deformation to increase the deformability.
