Abstract

The resistance of a modern ceramic material - silicon nitride - was examined by cyclical high temperature and compressive loads by the use of warm upsetting tests at cylindrical molybdenum and wolfram samples. Furthermore, flow curves of these samples were determined for different temperatures.
