Short time tensile tests were carried out at temperatures ranging from room temperature to 800°C on some austenitic stainless steels. The tensile strength and the elongation decreased with rising temperature up to 300°C, but they were almost constant at 300∼650°C. At this temperature range, a remarkable serrated discontinuous phenomenon appeared on the load-elongation curves. An observation of micro-structure of specimens after the high temperature tests showed the precipitation of chromium carbide along the slip bands, which was most remarkable in the specimen tested at about 600°C at which the serration of load-elongation curves was most remarkable. When chromium carbide is precipitated out during the test as fine particles, they act as a barrier for the motion of dislocations so that the slip is prevented for a moment, and this probably causes the break in the plastic deformation.
