%0 Journal Article %T STUDY OF PREVIOUS POWDER-PARTICLE BOUNDARY CARBIDES
%J 金属学报 %D 1987 %I %X The previous powder-particle boundary (PPB) problem has been studied in P/M superalloy FGH95. The results indicate that the PPB carbides begin to form on the powder surface during atomization and continuously precipitate during HIP-consolidation. As a result of complex composition of carbides the different types carbides interact probably. The amount of PPB precipitation increased significantly during post-HIP heat treatment. The formation of PPB carbides is related to the amount of residual oxygen in alloy. %U http://www.alljournals.cn/get_abstract_url.aspx?pcid=5B3AB970F71A803DEACDC0559115BFCF0A068CD97DD29835&cid=AB188D3B70B071C57EB64E395D864ECE&jid=B061E1135F1CBDEE96CD96C109FEAD65&aid=53E08D508A21F53B54939375D46C69CF&yid=9C2DB0A0D5ABE6F8&vid=EA389574707BDED3&iid=0B39A22176CE99FB&sid=D2742EEE6F4DF8FE&eid=1D01216AD76577EC&journal_id=0412-1961&journal_name=金属学报&referenced_num=0&reference_num=1
