PRODUCTION OF METALLIC POWDER

PURPOSE:To efficiently produce fine metallic powder having a low oxygen content by melting a metal having ductility or malleability at room temp., cooling drops of the molten metal with a gas or liq. at a specified solidification rate and subjecting the resulting powder to oxidation, mechanical fine...

description	PURPOSE:To efficiently produce fine metallic powder having a low oxygen content by melting a metal having ductility or malleability at room temp., cooling drops of the molten metal with a gas or liq. at a specified solidification rate and subjecting the resulting powder to oxidation, mechanical fine crushing and heat treatment in a reducing atmosphere. CONSTITUTION:A metal having ductility or malleability at room temp., e.g., an alloy consisting of 13wt% Cr, 1wt% Si and the balance Fe is melted to make drops. Drops of the molten metal is cooled with a gas or liq. at

CONSTITUTION:A metal having ductility or malleability at room temp., e.g., an alloy consisting of 13wt% Cr, 1wt% Si and the balance Fe is melted to make drops. Drops of the molten metal is cooled with a gas or liq. at <=10 deg.C/sec solidification rate so as to regulate the grain size of the resulting powder to <=30mum. The resulting powder is oxidized, mechanically finely crushed and heat treated in a reducing atmosphere. Thus, metallic powder having <=0.5% oxygen content and <=30mum particle size is produced.</description><language>eng</language><subject>CASTING ; MAKING METALLIC POWDER ; MANUFACTURE OF ARTICLES FROM METALLIC POWDER ; PERFORMING OPERATIONS ; POWDER METALLURGY ; TRANSPORTING ; WORKING METALLIC POWDER</subject><creationdate>1987</creationdate><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktohtml>$$Uhttps://worldwide.espacenet.com/publicationDetails/biblio?FT=D&date=19871125&DB=EPODOC&CC=JP&NR=S62270707A$$EHTML$$P50$$Gepo$$Hfree_for_read</linktohtml><link.rule.ids>230,309,781,886,25569,76552</link.rule.ids><linktorsrc>$$Uhttps://worldwide.espacenet.com/publicationDetails/biblio?FT=D&date=19871125&DB=EPODOC&CC=JP&NR=S62270707A$$EView_record_in_European_Patent_Office$$FView_record_in_$$GEuropean_Patent_Office$$Hfree_for_read</linktorsrc></links><search><creatorcontrib>HIDAKA KENSUKE</creatorcontrib><creatorcontrib>OKUMURA KATSU</creatorcontrib><title>PRODUCTION OF METALLIC POWDER</title><description>PURPOSE:To efficiently produce fine metallic powder having a low oxygen content by melting a metal having ductility or malleability at room temp., cooling drops of the molten metal with a gas or liq. at a specified solidification rate and subjecting the resulting powder to oxidation, mechanical fine crushing and heat treatment in a reducing atmosphere.
