Abstract

Abstract. A volume increase associated with the internal nitriding of Ni–5 at.% Cr alloy at relatively low homologous temperatures and high nitrogen fugacities results in a stress gradient between the alloy surface and the precipitation front. Stress relief occurred mainly by transport of nickel (solvent) to the stress-free metal surface mediated by pipe diffusion-controlled creep. This mechanism is prevailing because of a high dislocation density developing within the parent Ni-matrix upon the precipitation of semi-coherent nitride particles. The CrN-precipitates was found to be topotactically oriented with respect to the matrix
