Low-cycle Fatigue Properties of TiAl Intermetallic Compounds

HIGH-TEMPERATURE FRACTURE AND FATIGUE RESISTANCE OF A DUCTILE b-TiNb REINFORCED g-TiAl INTERMETALLIC COMPOSITE

ÐThe high-temperature fatigue-crack propagation and fracture resistance of a model g-TiAl intermetallic composite reinforced with 20 vol.% ductile b-TiNb particles is examined at elevated temperatures of 650 and 8008C and compared with behavior at room temperature. TiNb reinforcements are found to enhance the fracture toughness of g-TiAl, even at high temperatures, from about 12 to 040 MPa m, a...

Hydrogen storage properties of Ml, _,Ca,Ni, pseudobinary intermetallic compounds

The hydrogen storage properties of the pseudobinary intermetallic compounds Ml, -.Ca,Ni, (where Ml is La-rich mischmetal and x varies from 0 to 0.9) were investigated over the temperature range of 25-80°C It was found in experiment that with increasing x in Ml,_,Ca,Ni, the incubation time for its first hydrogenation shortened, the first hydrogen absorption rate accelerated, the hysteresis lower...

Ultra-Low Cycle Fatigue Fracture Life of a Type of Buckling Restrained Brace

Buckling restrained braced frames (BRBFs) for seismic load resistance have been widely used in recent years. One of the key requirements for a buckling restrained brace is to sustain large plastic deformations under severe ground motions. The core of a buckling restrained brace is prone to fatigue fracture under cyclic loading. The earthquake induced fracture type of the core plate in a bucklin...
