Abstract
THE creep behaviour of graphite in the temperature range 1,300–2,000° C. has been examined for the first time. The experiments were carried out by applying loads to cantilevers heated in vacuo by the passage of an electric current and to spring specimens heated in a high-temperature high-vacuum furnace. The specimens were made in the laboratory by extruding a wide range of raw materials (pitch coke, petroleum coke, lamp black, cellulose and natural graphite). Springs of rectangular section were also machined from commercially manufactured materials (reactor graphite and commercial electrode graphite). The apparatus and techniques used in these experiments were similar to those used in dynamic experiments previously described1.
