Abstract

Characterization Fully dense ceramics Microstructure evaluation Solid freeform fabrication
Characterization of mechanical, morphological and structural properties of compressive strength, Vickers micro-hardness, damage tolerance, thermal shock, and microstructure evaluation of Ti 3SiC 2 structures fabricated by the three-stage process of three-dimensional printing, cold isostatic pressurizing and sintering are presented. Experimental data show a linear deformation to failure behavior of the Ti 3SiC 2 specimens, and comparable properties of compressive strength, hardness, damage tolerance and thermal shock of the three-stage fabricated Ti 3SiC 2 structures to the reported data of Ti 3SiC 2 bulk. Results of mechanical characterization of Ti 3SiC 2 samples also reveal a process-induced anisotropy in compressive strength, damage tolerance and thermal shock properties.
