The diffusion of Ni and Cr into TD-NiCr has been studied over the 900 to 1100掳C temperature range. The diffusion couples were prepared by electroplating Cr and Ni on polished TD-NiCr wafers. Concentration profiles produced as a result of isothermal diffusion at 905, 1000, and 1100掳C were...

The annealing response of shock-loaded TD-Ni and TD-NiCr was dominated by the ThO2 dispersion acting as barriers to the climb and glide of shock-induced dislocations, which were limited during the shock deformation process in the same manner. While the Thoria-dispersed Ni and NiCr were ...
By using specially processed TD-NiCr sheet in both 0.4-mm (0.015-in.) and 1.6-mm (0.062-in.) thicknesses and carefully selected welding procedures, solid state resistance spot welds were produced which, after postheating at 1200 C, were indistinguishable from the parent material. Stress-...
