description PURPOSE:To manufacture a compound sintered body free from segregation and impurities and having high density at high yield by pulverizing a Ti-Al intermetallic compound having a specified compsn. obtd. by a combustion synthe sizing method into specified grain size, compacting this powder and executing specified sintering. CONSTITUTION:The powder of Ti, Al or the like is mixed and is subjected to combustion synthesizing to obtain a Ti-Al intermetallic compound contg., by atom, 20 to 80% Al and, according to necessary, furthermore contg. one or more kinds among 0.1 to 5% V, 0.1 to 5% Nb, 0.1 to 5% Mn, 0.03 to 3% B, 0.1 to 5% Ag and 0.1 to 1% Si. This Ti-Al intermetallic compound is pulver ized into

This Ti-Al intermetallic compound is pulver ized into &lt;=100 mesh. The green compact obtd. by compacting the above powder is sintered at 1,350 to 1,450 deg.C for 1 to 3 hr in high vacuum. In this way, the compound sintered body free from segregation, having a fine and homogeneous compsn., free from cracks and having denseness can be obtd. This sintered body is light in weight, excellent in heat resistance, electrical conductivity, environmental corrosion resistance, high temp. strength or the like and is suit able as the material for high temp. machine members, electrodes and parts for chemical plants.</description><edition>6</edition><language>eng</language><subject>ALLOYS ; CHEMISTRY ; FERROUS OR NON-FERROUS ALLOYS ; METALLURGY ; TREATMENT OF ALLOYS OR NON-FERROUS METALS</subject><creationdate>1998</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&amp;date=19980408&amp;DB=EPODOC&amp;CC=JP&amp;NR=2738766B2$$EHTML$$P50$$Gepo$$Hfree_for_read</linktohtml><link.rule.ids>230,308,776,881,25542,76516</link.rule.ids><linktorsrc>$$Uhttps://worldwide.espacenet.com/publicationDetails/biblio?FT=D&amp;date=19980408&amp;DB=EPODOC&amp;CC=JP&amp;NR=2738766B2$$EView_record_in_European_Patent_Office$$FView_record_in_$$GEuropean_Patent_Office$$Hfree_for_read</linktorsrc></links><search><creatorcontrib>MISHIMA AKIRA</creatorcontrib><creatorcontrib>SHIDE HIDEJI</creatorcontrib><creatorcontrib>SAKAGUCHI SHIGEYA</creatorcontrib><title>JP2738766B</title><description>PURPOSE:To manufacture a compound sintered body free from segregation and impurities and having high density at high yield by pulverizing a Ti-Al intermetallic compound having a specified compsn. obtd. by a combustion synthe sizing method into specified grain size, compacting this powder and executing specified sintering.
