At&tad--A technique for determining the thermal shock resistance ofhighly inhomogeneous industrial carbon materials has been developed. The technique is based on the controlled imposition of internal transient temperature gradients in a disk-shaped test specimen by conducting a constant direct cu

This paper presents a technique to determine the thermal shock resistance of graphite by a basic analysis of non-steady thermal stress in a circular disk heated by an arc discharge at its central part. The thermal shock resistance is defined as A = cr,k/Ea, (a,, circumferential tensile thermal stres
This paper presents a number of different methods for determining the mar resistance of automotive clearcoats. The various methods are compared on the basis of measurements on different clearcoat systems and the results discussed with other physical parameters (microhardness, crosslinking density).
The variations in several thermal and mechanical properties were examined for a large cylinder of CFZ graphite and several small cylinders of ATJ graphite. These property variations were correlated with bulk density, location in the ingot, orientation and in some cases, flaw occurrence as observed b
The "steady" sinusoidal technique employed previously to determine the thermal diffusivity in carbons has been improved and its temperature range extended. In this technique a sinusoidal heat input occurs at one end of a thin walled tube placed in a uniformly heated container and the variation in te
