Tensile Properties and Notch Toughness of Groove Welds in Wrought and Cast Aluminum Alloys at Cryogenic Temperatures
An impressive amount of literature has been developed to define the tensile properties and notch toughnesses of aluminum alloys at very low cryogenic temperatures [1–3], Data and service experience are consistent in indicating the suitability of many aluminum alloys for cryogenic service, since they retain their relatively high ductility and notch toughness, in addition to having useful strengths at very low temperatures. Although a fair amount of data have been presented on the tensile properties and notch toughness of welds in aluminum alloys [4,5], none have been available for liquid-helium temperature to provide a guide as to which particular combinations of parent and filler alloys might be most desirable for extremely low-temperature service.
