Impact of High Pressure Hydrogen Atmosphere on the Mechanical Properties of Haynes 282 Superalloy
Haynes 282 alloy is a newly developed nickel-base superalloy, with properties focussed on high creep strength, thermal stability, good weldability and fabricability, which might qualify it as a substitute for established materials like Hastelloy-X or René-41 e.g. in aerospace applications. However, so far no information on the sensitivity for hydrogen environement embrittlement (HEE) has been published for this material. In the present work, tensile tests in hydrogen atmosphere have been carried out at room temperature and the results have been compared to those from tests in argon. Haynes 282 is found to show significant hydrogen embrittlement.
