Optical microscope, transmission electron microscope (TEM) and scanning electron microscope (SEM) were used to investigate the relationship between microstructures and room-temperature tensile plasticity.

Effects of long-term aging on microstructure and room-temperature tensile property of alloy GH4586B

The microstructures and properties of Ti17 alloy joints welded by inertia friction welding(IFW) were investigated by room-temperature tensile test,high-temperature tensile test and metallographic analyses.

Effect of Heat Treatment on Tensile Plasticity of GH188 at 650℃;

Fracture mechanics of tensile ductility of TiAl alloy with duplex structure;

Alloy with low Fe content has high tensile ductility and the fracture emerges entirely transgranular behavior.

The experimental results show that fracture toughness is controlled by microplastisity in the small local region (1 to 2 times the crack tip opening displacements c at critical) ahead of the crack tip, whereas blunt notch toughness, tensile ductility is controlled by austenite grain size (dγ) or martensite packet diamiter (dp).
