Abstract Scope |
The use of miniature specimens accelerates the development and assessment of mechanical properties of new fuel cladding alloys for next-generation nuclear reactors, addressing limitations on available material volume during alloy development and irradiation experiments. However, there is a lack of testing systems which can perform mechanical tests on miniature specimens. Furthermore, no test system available can perform in-situ scanning electron microscope (SEM) high-temperature creep tests on miniature specimens for real-time characterization. To fill this gap, we developed a novel creep tester capable of performing in-situ SEM tests.
This work discusses the challenges in developing the miniature test equipment and highlights its capabilities. The test results of ex-situ and in-situ tests on miniature specimens of SS316 and alloy Kanthal APMT are presented. In addition, we discuss material characterization and crystal plasticity models used to simulate viscoplastic responses. |
