✦ Synopsis

Tensile strength and ductility were measured on commercial grade graphites with different grain sizes. Creep behavior was analysed by the following equation: E = B log t+ct. The data were measured by the umspecimen method. The samples annealed after creep gave the same creep curve at the secondary loading as at the first one. The parameter of strain hardening was found for the description of step creep curves. The parameters B and C were determined as functions of stress and temperature.

In contrast, the graphites having crystallites which possess good threedimensional order have a large, rather broad internal friction peak near room temperature, The height of this peak varies from 50 to 1 IO x IO4 depending upon crystallite size and the previous the

Acoustic emission (AE) was measured on four kinds of isotropic graphites under tensile and compressive loading. Observed AE events can be divided into two types, with low and high relative energy. The events with low relative energy were initially observed under a low stress level, continued to the

Specimens of two commercial graphites were hot-isostatically pressed at 2700°C to more than 95 per cent of theoretical density. These were compared in creep to unpressed specimens from the same artifact. The creep curves were similar in shape; strengths were equal, creep ductilities were equal, and
