| Abstract | Research activities on deformation and fracture characteristics of the Ti-Al intermetallics have assumed considerable significance in view of many potential applications as high temperature structural materials. These aspects are discussed in respect of two Ti-Al intermetallics with duplex and lamellar structures. The fracture toughness, crack growth resistance and fracture mechanisms are evaluated at room temperature. The differences in the behaviour of the alloys are explained in the light of microstructures as observed for the alloys. |
