Replacing some of the metallic iron by ferric oxide, Fe2O3, in the charge for the preparation of Kh18N15 and Kh23N28 stainless-steel powders by the calcium-hydride reduction process increases (two- to threefold) the yield of the fine fraction (-0.063

Additions of boron substantially increase the thermal conductivity of titanium. A linear relationship is observed between the thermal conductivity of titanium-boron alloys and their boron content. It must be emphasized, however, that the rise in the
