Fracture toughness of TiAl-Cr-Nb-Mo alloys produced via centrifugal casting

Fracture toughness of TiAl-Cr-Nb-Mo alloys produced via centrifugal casting

Show other versions (2)

Fracture toughness of a TiAl base intermetallic alloy has been investigated at room temperature. The Ti-48Al-2.5Cr-0.5Nb-2Mo (at. %) alloy produced via centrifugal casting exhibits fine nearly lamellar microstructures, consisting mainly of fine lamellar grains, together with a very small quantity of...
