Embodiment 1
[0023] The Ni powder and W powder with a purity of 99.99% are respectively proportioned according to the ratio of the atomic percentage of W to 7% and 9.3%; Grind in a planetary high-energy ball mill with a hydrogen protective atmosphere until they are evenly mixed; put the mixed powders of two different proportions into an intermediate frequency vacuum induction furnace with a protective atmosphere for melting to obtain two Ni-W alloys with different W contents Ingot casting; then two kinds of Ni-W alloy ingots are obtained through hot forging and hot rolling; two initial ingots with the same size and a thickness of 1mm are obtained by wire cutting; The ingot was cold-rolled to 0.5mm, the deformation of each pass was controlled at 5%, and the total deformation was 50%, so as to obtain two cold-rolled ingots with the same thickness; the Ni-W alloy ingot with low W content after cold rolling was recorded as is A, and the Ni-W alloy ingot with high W content is denoted as B; the...
