Original abstract

Role of microstructure in fracture performance of TiAl intermetalics at room and elevated temperatures is analysed in the paper. Tensile properties, flexural strength and fracture toughness have been evaluated for Ti40Al2Cr2Nb1B and Ti46Al0.7Cr0.1Si7Nb0.2 Ni alloys. Extensive development of shear ligament toughen-ing was observed supplying quite good fracture toughness values in high Nb alloy. Based on findings obtained key aspects of the effect of separate microstructural components have been discussed.

Keywords in English

fracture toughness, micromechanisms of fracture, shear ligament toughening, TiAl, intermetalics.
