Abstract

<PICT:0985602/C6-C7/1> The absorption of hydrogen by titanium and titanium base alloys exposed in service to hydrogen atmospheres at temperatures up to 400 DEG C. is minimized by maintaining in the said atmosphere 0.1-1% by volume of oxygen and/or water vapour. The titanium alloy may contain 5-30% of at least one of the metals aluminium, tin and zirconium.
