Effect of hydrogen treatment on microstructures and properties of weld metal in TA15 alloy;

Effect of hydrogen treatment on microstructure and room temperature deforming properties of TC4 Ti alloy;

Effects of hydrogenation for polycrystalline SiGe (poly-Si1-xGex) thin films were estimated by investigating the dark conductivity and activation energy that derive from the conductivity as a function of the temperature.

Based on analysis of the characteristic,shape of squeeze roller and the prevention and cure of "grain inheritance" and dehydrogenation of the heavy squeeze roller made of 42CrMo steel,the heat treatment process including one time of pretreatments,two times of preheating,two times of normalizations,three times of bainite isothermal treatment and one time of dehydrogenation,was proposed.

In the case that the dehydrogenation is not sufficient, the residual hydrogen led to the spring hydrogen-induced delayed fracture.
