Abstract

The concept of ductile-phase toughening was explored in a metallic-intermetallic laminate (MIL) composite comprising alternating layers of Ti₃Al and TiB_w/Ti. The laminates, in which the TiB_w/Ti layers were intended to impart toughness to the brittle Ti₃Al, were fabricated in situ by hot pressing and reaction annealing. Compared with monolithic Ti₃Al, the MIL composite exhibited marked increases in both fracture toughness and tensile elongation because of stress redistribution and strain delocalization by in situ interfaces.
