ELEVATED TEMPERATURE DEFORMATION BEHAVIOR OF IN SITU MULTIPHASE COMPOSITE (NiAl-28Cr-6Mo)TiC
原位内生多相复合材料（NiAl—28Cr—6Mo）—TiC的高温力学行为

An intermetallic matrix composite (NiAl-28Cr-6Mo)-TiC has been successfully fabricated by using reaction synthesis method. The elevated temperature deformation behavior of the in situ multiphase composite was investigated. The flow stress decreases with increasing temperature or decreasing initial strain rate. The deformation behavior of the composite can be adequately described by the power law. The stress exponent and activation energy are calculated and compared with other similar NiAl-based composites.
