Abstract:

Creep testing at elevated temperatures is an expensive and time-consuming business. Nevertheless, creep tests are frequently duplicated, there appears to be little confidence in creep data obtained from other laboratories. This lack of confidence is due in part to the extreme variability of the creep properties, which exceeds that of the other mechanical properties of the materials most commonly used. However, differing laboratory techniques and specifications give rise to uncertainties as to the amount of scatter that should be attributed solely to the variability of the material properties. The AGARD Working Group on High-Temperature Material Testing was established in 1966 with the aim of improving the specifications and raising the standard of determination of the mechanical properties of materials at high temperatures in the NATO countries. The report describes the results accomplished. Author
