| Outline of Final Research Achievements |
A creep damage evaluation under multiaxial stress conditions is required to ensure the integrity of high-temperature structural components such as boiler pipes of thermal power plants and turbine blades of aircraft engines.
In order to solve these issues, a new method of high-temperature multiaxial creep experiments is established in this work.
Particularly in the field of material evaluation and testing, we challenged the use of small size specimens because the miniaturization of the material size to be evaluated is effective in improving its accuracy. A cruciform specimen, which has 50 mm x 50 mm size was designed, and a testing system was developed for this specimen to establish a high-temperature multiaxial creep testing. A major feature of this system is that the deformation and strain of a specimen in a high-temperature electric furnace can be measured by a non-contact investigation system using an optical camera.
