Ti₃SiC₂-(Ti₃SiC₂-SiC) functionally graded materials by spark plasma sintering reactive synthesis method Part 2 - Fabrication and characterization

Ti₃SiC₂-(Ti₃SiC₂-SiC) functionally graded materials were in situ fabricated successfully by the method of spark plasma sintering reactive synthesis which was found to be applicable for the fabrication of functionally graded materials with good graded composition, microstructure as well as hardness distribution. It was also shown from the characterisation results that, with the increase in intermediate grade layers, the cracks due to residual thermal stress tend to be reduced, which is consistent with former finite element analysis results.
