“…The impression creep test is also able to produce a large volume of useful data from small amounts of material which include the ability through stepped-load and stepped-temperature tests to multiple sets of minimum creep strain rate data from a 10 × 10 × 2.5 mm test specimen, useful in alloy development. 2 10 Distribution of impression creep strength of specimens a as-sampled b corrected to start of life 11 11 Blade root, with specimens removed by spark erosion and b Log-log plot of stress as a function of minimum strain rate, for a small ring and uniaxial tests at 800°C 27…”

“…Current tests still depend on some form of uniaxial data tested on a material or component of choice, although in some cases once the data is obtained the small specimen creep tests can then operate independently using the uniaxial data as a reference point. In addition due to the small amounts of material obtained, small specimens have the potential to be used in novel alloy development [2,3].…”

Small specimen creep testing techniques are novel mechanical test techniques that have been developed over the past 25 years. They mainly include the sub-size uniaxial test, the small punch creep test, the impression creep test, the small ring creep test and the two bar creep test. This paper outlines the current methods in practice for data interpretation as well as the state of the art procedures for conducting the tests. Case studies for the use of impression creep testing and material strength ranking of creep resistant steels is reviewed along with the requirement for the standardization of the impression creep test method. A database of small specimen creep testing is required to prove the validity of the tests.
