METHOD OF MANUFACTURING HOT-DEFORMED ARTICLES FROM POWDER MATERIALS Russian patent published in 2000 - IPC

Abstract RU 2151025 C1

FIELD: powder metallurgy, particularly, manufacture of hot-deformed low-porous articles including those made from ready oxidizable materials. SUBSTANCE: method includes molding of article blank placing it into process container, heating and hot-quazi-isobar final compaction of blank in container. Molded blank is finally compacted by cold quasi-isobaric pressing with simultaneous formation of process container from powdery composite material based on aluminum oxide and glass. EFFECT: higher efficiency. 5 cl, 1 ex
