中文摘要	The pressure-volume-temperature measurements were carried out for titanium carbide (TiC) at pressures and temperatures up to 8.1 GPa and 1273 K using energy-dispersive synchrotron x-ray diffraction. Thermoelastic parameters were derived for TiC based on a modified high-temperature Birch-Murnaghan equation of state and a thermal pressure approach. With the pressure derivative of the bulk modulus, K(0)('), fixed at 4.0, we obtain: the ambient bulk modulus K(0)=268(6) GPa, which is comparable to previously reported value; temperature derivative of bulk modulus at constant pressure (partial derivative K(T)/partial derivative T)(P)=-0.026(9) GPa K(-1), volumetric thermal expansivity alpha(T)(K(-1))=a+bT with a=1.62(12)x10(-5) K(-1) and b=1.07(17)x10(-8) K(-2), pressure derivative of thermal expansion (partial derivative alpha/partial derivative P)(T)=(-3.62 +/- 1.14)x10(-7) GPa(-1) K(-1), and temperature derivative of bulk modulus at constant volume (partial derivative K(T)/partial derivative T)(V)=-0.015(8) GPa K(-1). These results provide fundamental thermophysical properties for TiC for the first time and are important to theoretical and computational modeling of transition metal carbides.
