Last month I’ve made a second attempt towards in situ formation of AlN reinforcement in aluminium matrix. The experiment involved melting of aluminium in Balzers type induction furnace, and then, after removal of surface oxide layer, introduction of nitrogen-bearing substrate (in form of a green compact) to the metallic melt. Unfortunately, apart from eddy currents, there was no possibility of mixing the melt, which was the reason why the substrates remained on the surface of aluminium. As a result, aluminium nitride was found only in the surface layer of the material.
