Abstract

The mechanical properties at the interfaces of TiC_xNiAl composites with four different C/Ti ratios fabricated by pressureless melt-infiltration processing were investigated using the nanoindentation technique. We find that the nanohardness and the elastic modulus from the TiC_x phase to the NiAl phase have a gradient distribution. Both the elastic modulus and nanohardness at the interface reached higher values at x = 0.75. The topography of the sample was analysed by scanning force microscopy.
