Grain boundaries in high-purity silicon carbide bicrystals produced by sublimation-deposition at 2800 K were examined by high-resolution transmission electron microscope (HRTEM). Two asymmetric tilt boundaries with a rotation of 70–5° about [1100]

Using new proposals regarding the stability condition of cracks in a brittle material and the rate equations for heterogeneous system, numerical calculations are performed on the rate of crack propagation and the time to failure in silicon carbide si

So as to treat brittle faracture by an atomic model, problems in the energy equilibria on the crack stability and those in the rate process are discussed, and new expressions are proposed. Newly derived critical condition of crack propagation for Gri

Crack tip geometries in covalent crystals were studied by high resolution (HR) TEM. The materials used in the study were SiC, Si crystals and 15R-sialon grain. Cracks were introduced by Vickers indentation in SiC and Si. In 15R-sialon, crack was natu

Problems in the expression of the Thomson-Freundlich equation are discussed, and it is shown that solubility or the vapour pressure in equilibrium with the spherical particle must be expressed as follows, ln (X/X0)=(3Vei/γRT)andln(P/P0)=(3Ves/γRT)W

The reaction sintering of β-sialon (Si4Al2O2N6) from a powder mixture of Si3N4, Al2O3 and AIN was studied to clarify factors affecting the densification. The presence of sufficient SiO vapour on the compact and excess oxide with respect toβ-sialon

We proposed an atomic configurational model on an asymmetric boundary between 3C (111) and 6H (1012) faces of SiC single crystals. In this model, the boundary energy was estimated with the numbers of dangling bonds at the boundary with different ener

An extended formulation of rate equation is proposed so as to treat the rate process in a heterogeneous system, such as crack propagation velocity in brittle fracture. The proposal can be applied for a process in which the excess energy stored in the
