  • Metal powder suited for powder metallurgical purposes, and a process for manufacturing the metal powder
    Patent number: 4069045
    Abstract: A steel powder suited for powder metallurgical purposes consists of an amorphous to compact-grained, essentially dendrite-free material with irregularly cornered particle shape. Such a steel powder may be produced by causing molten steel to form at least one discrete, relatively thin film on a relatively cold metal surface of great cooling capacity, causing the thin film to solidify extremely rapidly on the metal surface to form a brittle amorphous to compact-grained, in principle completely dendrite-free steel film, and crushing or grinding the brittle film into a powder of an irregularly cornered particle shape.

  • Metal flake product suited for the production of metal powder for powder metallurgical purposes, and a process for manufacturing the product
    Patent number: 4063942
    Abstract: A steel flake product, suitable for being crushed or ground to form a steel powder for powder metallurgical purposes, consists of a plurality of relatively thin, brittle and easily crushed, substantially dendrite-free steel flakes of amorphous to compact-grained structure. Such steel flakes are produced by causing molten steel to form at least one discrete, relatively thin flake-shaped layer on a relatively cold metal surface of great cooling capacity, moving rapidly and substantially across the direction of delivery of the molten steel. Due to the great cooling capacity the layer is made to solidify extremely rapidly.
