A review of directionally solidified intermetallic composites for high-temperature structural applications Academic Article uri icon

abstract

  • Alloys based on intermetallics have been considered for high temperature structural applications. However, many of these alloys suffer from intrinsic brittleness and low fracture toughness at ambient temperature. Therefore, ductile-phase-toughened intermetallic composites are being investigated as a means to improve the fracture toughness. A subset of this class of materials is in-situ composites produced by directional solidification of intermetallic eutectics. In this paper, we review recent developments related to the processing and properties of these composites. © 2004 Kluwer Academic Publishers.
