Haynes 282 is a novel Ni-base superalloy, combining excellent weldability and general processability with moderate cost. As such, it is very promising for e.g. industrial gas turbines, aero engines or advanced ultra-supercritical boilers, where increased combustion temperatures are essential to improve the efficiency and reduce emissions. However, the combination of weldability and low-temperature ductility could also make it a candidate for e.g. pressure vessels in critical applications for different liquefied gases such as hydrogen, oxygen, nitrogen or natural gas. However, the knowledge of the behaviour of superalloys at cryogenic temperatures is limited, in particular with respect to changes in the deformation mechanisms. We propose to do in-situ mechanical testing of Haynes 282 at cryogenic temperatures to study the low-temperature behaviour of different microstructures
