摘要： A process is provided for a technologically controllable, economic production of hard-magnetic parts from Sm.sub.2 --(Fe,M).sub.17 --C.sub.y -base work materials with interstitial inclusions, where M designates gallium and/or at least one metallic element serving to stabilize a rhombohedral 2:17 structure. A Sm.sub.2 Fe.sub.17-x M.sub.x C.sub.y powder mixture is produced, where x>0.1 and 3.gtoreq.y.gtoreq.0. The mixture is subjected to an intensive fine grinding process in a ball mill. The finely ground mixture is heat-treated in a temperature range from 650.degree. C. to 900.degree. C. for partial or complete recrystallization. The resulting ultra-fine-grain Sm.sub.2 Fe.sub.17-x M.sub.x C.sub.y magnetic powder is compacted to produce magnet bodies by a hot pressing processing in a temperature range from 650.degree. C. to 900.degree. C. The process is applicable, for example, for the production of hard-magnetic parts based on interstitial Sm.sub.2 Fe.sub.17 C.sub.y compounds.

摘要： A superconducting oxide film is prepared by a method of seeding formation and heat treatment which comprises depositing a layer of a metal-oxide precursor on a predetermined substrate, forming a seed of a predetermined superconducting phase only in a locally limited region of the metal-oxide precursor at a boundary surface to the substrate by means of a solid-state reaction triggered by pulsed energy radiation, and then at least partially converting the metal-oxide precursor into the desired superconducting metal-oxide phase by a heat treatment in the oxygen atmosphere at a temperature below 800.degree.

摘要： A metal part, which may be an amorphous metal, is formed from an intermediate product comprised of at least two alloy components in powder form which have been compacted and optionally deformed such as by hammering or extrusion. The intermediate part is transformed into the metal part by a diffusion reaction. The intermediate product is produced by milling the at least two starting alloy components to form a mixture powder of particles having a predominantly layer-like structure comprising the starting alloy components. At least one of the starting alloy components is magnetic. After milling, the produced mixture powder is subjected to a magnetic field which aligns the still mobile powder particles. Thereafter, the final compacting and possible deformation takes place.
