Abstract (en)

[origin: DE102005013368B3] A blank starting product is made via a melt- or powder-metallurgical route, whilst taking mechanical alloying into account. The blank comprises technically-pure nickel or nickel alloy that contains a silver addition in the micro-alloy range of 10 atom ppm to 1000 atom ppm. The blank product is worked initially by hot deformation, then by cold deformation. Deformation exceeds 50% thickness reduction to strip or flat wire, with an intermediate dimension. This is stress-relieved by annealing at 500-850[deg]C, the higher temperatures being used for higher silver contents. The blank is quenched. It is subjected to substantial cold deformation exceeding 80%. Recrystallization annealing follows, resulting in the fully cubic structure.
