Influence of elevated temperature on hydride formation and hydrogen-assisted deformation in pure titanium

Abstract The effect of temperature on hydride formation and hydrogen-induced deformation in α-Ti was investigated using tensile testing combined with in-situ SEM observations. Microstructural characterization of hydrogen-charged and deformed specimens at both room temperature and...

Effect of gaseous hydrogen on embrittlement of PBF-LB alloy 718: Influence of build orientation and microstructure on mechanical properties

This study reports the effects of build orientation and precipitates on the hydrogen embrittlement susceptibility of powder bed fusion – laser beam (PBF-LB) alloy 718 for aerospace applications. The material is subjected to hot isostatic pressing (HIP) then to a modified aerospac...
