✦ Synopsis

Tensile and symmetrical push-pull fatigue tests were conducted on commercially pure titanium containing ␥ hydrides. The plastic deformation of ␥ hydrides was observed in both tensile and cyclic tests. Voids were found to nucleate at hydrides in heavily deformed tensile specimens. The macroscopic mechanical behaviors correlated with the evolution of microstructure were investigated. It was found that the specimens and the embedded hydrides were fractured in a typical ductile manner. And the effect of ␥ hydrides on cyclic and tensile properties of titanium containing such a low hydrogen concentration (77 ppm) is negligible.

Low-cycle fatigue tests have been carried out on annealed commercially pure titanium under strain-controlled conditions. The relation between a plastic strain range and a number of cycles to failure obeyed Manson-Coffin's rule. The initiation of fatigue cracks was observed successively with the aid
