Abstract:The paper investigates the use of the hot axisymmetric compression test for the determination of the hot working properties of alloys. Qualitative analysis shows that stress determinations from the test are subject to systematic errors. These arise from frictional effects and deformation heating. The errors are affected by the conditions of the test and the effects of these parameters have been investigated using a fully coupled finite element procedure. Specimen geometry, specimen volume, friction, temperature, strain rate, and strain have been investigated. Procedures outlining methods of error calculation for general testing conditions are given. Methods of using the data to correct stress–strain curves, to validate such curves and to optimise testing conditions are discussed.
