Abstract
A stress-relaxation machine has been developed capable of providing very precise results throughout the useful temperature range of common structural metals. Among the advantages claimed for this machine are: dynamic response, sensitive control, and low cost. It is demonstrated that with the use of a single specimen and relatively short testing times, a complete set of stress- strain rate values can be obtained at any desired temperature. The reliability of the testing device and the analytical model is shown in the comparison of values predicted from relaxation tests with those obtained in constant-stress creep tests. It should be emphasized that the relaxation test is not a substitute for the creep test. However, it does provide a check on the accuracy of the law assumed for the constant-stress creep data and provides additional information which assists the metallurgists in establishing more exact analytical models to describe the deformation process.
