Development of strong and tough cryogenic Fe-12Ni alloys containing reactive metal additionsThe fracture toughness and tensile behaviour of arc-melted and hot-rolled Fe-12Ni alloys containing up to 4 atomic percent reactive metal additions of Al, Nb, Ti, or V were determined at 77 K. Cryogenic toughness was improved up to 7.5 times that of binary Fe-12Ni, depending on the reactive metal, its concentration, and annealing temperature.
