摘要：

In this paper, a Ti-Al3Ti core-shell structured particle reinforced pure Al based composite was fabricated by powder metallurgy technique. The composite has high compressive strength and ductility since the interface is clean and tight, and the propagation of the nucleated cracks in the shell during deformation can be effectively inhibited by soft Al matrix and Ti core. Although the residue pores and voids readily develop into large-sized pores in the matrix under tension, the composite still shows promising tensile mechanical properties. (C) 2015 Elsevier B.V.
