TiB PARTICLE REINFORCED Ti2AlNb INTERMETALLIC COMPOUND MATRIX COMPOSITE MATERIAL AND ITS PRODUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a lightweight, high strength composite material excellent in Young's modulus, high temperature tensile characteristics and creep characteristics in high temperatures without deteriorating its room temperature characteristics.;SOLUTION: This Ti2AlNb intermetallic compound matrix composite material having a metallic structure essentially consisting of an O phase as the ordered phase of rhombic crystals, and in which TiB particles are finely dispersed is produced by using an alloy material in which TiB particles are previously dispersed to produce alloy powder by rapid solidification by a gas atomizing method and next compacting the same.;COPYRIGHT: (C)2002,JPO
