TITANIUM-ALLOY MATERIAL POSSESSING HIGH RESISTANCE TO HYDROGEN ABSORPTION

摘要

FIELD: metallurgy; titanium alloys used in media where risk of breakage due to hydrogen absorption is present. ^ SUBSTANCE: proposed titanium-alloy material contains 0.5-3.0 mass-% of aluminum at thickness of layer of 0.10-30 mcm with increased content of Al which is formed in solid part of material; content of Al in this layer exceed content of Al in solid part of material by 0.3 mass-% and more and content of Al in layer ranges from 0.8 to 25 mass-%. This material may be used in media where risk of embrittlement due to hydrogen absorption is present. After cold treatment, material possesses the same properties as pure titanium. ^ EFFECT: enhanced efficiency. ^ 5 cl, 3 tbl, 1 ex
