revious studies have shown that hydrogen has a detrimental effect on the mechanical properties of titanium aluminides Ti;In order to better understand the effects of hydrogen on the mechanical properties in these alloys, a study of the hydrogen effects on the microstructure of the Super-;Three Ti-25Al-10Nb-3V-1Mo microstructures were tested in tension for hydrogen contents ranging from 300 wppm to 2900 wppm. For low hydrogen contents, hydrogen induced a loss in ductility without significant increase in strength, and it is proposed that hydrogen increased slip planarity in the... |
