A calculation is presented of the hexagonal axis thermal expansion coefficient of a graphite crystal up to 1000Β°K using the measured values of two of the three anharmonic coefficients which affect the out-of-plane acoustic vibrational mode. The third anharmonic coefficient (&/ae,,), which is determi

A calculation is made of the effects on the hexagonal axis thermal expansion coefficient of a graphite crystal of the changes in the interlayer forces due to the large inter-layer expansions. It is found that the expansion coefficient is significantly increased at temneratures above 800Β°K and that t
Los Angelse, California). An investigation has been undertaken to understand the mode of failure of graphites as a function of their microstructure and to correlate the experimental observations with a theory of failure based on the coincidence alignment of microstructural defects. SEM observations
