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...
