FABRICATION OF DENSE TiB2/NiAl INTERMETALLIC COMPOUND-MATRIX COMPOSITES BY SHS+HP
-
Abstract
SHS+HP method was used for fabricating IMCs reinforced with TiB2 ceramic particles.XRD,SEM and Image analysis were used for studying the microstructure of samples.The results show that SHS process is specially suitable for IMCs reinforced by particles.The average grain size of TiB2 in TiB2/NiAl composites is about 0.8μcm,The porosity of the composites is less than 1.0%.
