Abstract：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. 收稿日期: 1987-02-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 李慧英 胡本芙 章守华 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1987/V23/I2/212 1 Ingesten N G, Warren R, Winberg L.
