METHOD FOR MAKING SEMIFINISHED PRODUCTS FROM FAST-CRYSTALLIZED MAGNESIUM ALLOYS Russian patent published in 1995 - IPC

Abstract RU 2035261 C1

FIELD: powder metallurgy. SUBSTANCE: invention permits expanding the technological possibilities of preparation of semifinished products due to hot extrusion at a low drawing coefficient by carrying out precompaction at a briquette temperature of 423-473 k and a container wall temperature of 623-653 K while retaining the ratio between precompaction container diameter and the briquette diameter within 1.1-1.3. EFFECT: method can be utilized for making large-section blanks from strips. 2 tbl
