A highly stable dispersion of TiN was produced in molybdenum by the isothermal heat treatment in nitrogen of a 1% Ti-Mo alloy in the temperature range 1100to 1500 gas-cooled C. The dispersed phase was studied metallographically, and microhardness traverses made of the diffusion layer. The hardness of the sunface layers was approximately doubled. but the microhardness fell on passing inwards from the surface. The results are discussed in terms of the relation between hardness, particle sizes. and diffusion rates. (auth)
