Purpose and goal

The purpose is to develop and validate an efficient assessment tool for the industry to characterise and evaluate high-temperature materials.

Expected results and effects

Expected results are the acquisition of experimental evidence for that the creep deformation, which usually is measured in conventional creep testing, is possible to extract from SSRT (slow strain rate testing) tests by post-processing of the test data based on theoretical hypotheses. The outcome is expected to be the severe reduction in test time and associated costs when developing new high-temperature materials since SSRT testing potentially can replace conventional creep testing.

Planned approach and implementation

Mechanical testing involving conventional creep and SSRT testing will be conducted on three different materials; a nickel-based superalloy, a stainless steel and a ductile cast iron. The SSRT test data will then be analysed starting from two hypotheses regarding how creep deformation can be extracted. The validity and reliability for the different extraction methods will be evaluated by comparison to the performed conventional creep testing.
