“…The first studies of strength and elastic properties for the transition metal carbide-carbon HMC [7][8][9][10][11][12][13][14][15][16][17] began simultaneously with the initial development of different manufacturing methods (hot pressing/sintering, [7][8][9]15,17,18 arc casting, [10][11][12]17 chemical vapour deposition 13,16 and melt/chemical vapour impregnation/infiltration of carbon structures 14,19 ) for preparation of these materials. The main goals of the measurements were to find out the general correlations between the employed technological parameters and some mechanical properties of the newly produced composites, and thus, by means of it to improve/optimise a manufacturing technique.…”

Highly densified TiC, ZrC and HfC based ultrahigh temperature heteromodulus ceramics (HMC), containing 10-50 vol.-% of low modulus phase in the form of particulate graphite, were prepared by hot pressing at 2700uC 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.
