Shabalin, I L & Wang, Y & Krynkin, A V & Umnova, O & Vishnyakov, V M & Shabalin, L I & Churkin, V K 2010, 'Physico-Mechanical Properties of Ultra-High Temperature Hetero-Modulus Ceramics Based on the Group 4 Transition-Metal Carbides', Advances in Applied Ceramics, 109(7), pp.405-415.
Highly densified TiC-, ZrC- and HfC-based ultra-high temperature hetero-modulus ceramics (HMC), containing 10-50 vol.% of low-modulus phase in the form of particulate graphite, were prepared by hot pressing at 2700 ºC and 12 MPa in argon atmosphere. The microstructure, elastic characteristics, flexural and compressive static strength, fracture toughness, impact resistance, hardness and thermal expansion were investigated and compared with those available in earlier works for clear understanding the composition-property correlations and anisotropy of this type of HMC composites. Different thermal shock resistant parameters for the HMC were calculated on the basis of obtained experimental data. A new principle of optimum materials design for the compositions in the refractory carbide – graphite systems is exemplified by the TiC – C HMC materials.
