and smooth areas) with different features are alternatively distributed on the whole fracture surface. The dimple areas originate from voids generation and coalescence, exhibiting ductile fracture... along grain boundaries and exhibits brittle fracture characteristics. Fracture occurring in adiabatic shear bands is not uniform and ultimate rupture is resulted from ductile and brittle fracture modes......
investigations have demonstrated that the fracture toughness of TiAl alloys was improved by intrinsic and extrinsic toughening mechanisms [6]. Intrinsic toughening arises from matrix slip and ductile phase... to influence the fracture resistance of these alloys [7]. In addition, the fracture toughness of brittle material can be improved by incorporating ductile reinforcement, an approach that is known as ductile......
