A creep test rig is described which allows to perform creep experiments with miniature tensile creep specimens under an inert gas atmosphere at temperatures up to 1150°C. Previous work on the development of a miniature tensile creep test procedure is described. The key elements of the new inert gas system are then described. The test rig yields reliable creep data. Three examples for applications of the new system addressing grain boundary sliding in a TiAl alloy, creep cavitation and damage accumulation in copper and to provide high temperature creep data for a Co‐Re‐Cr alloy are given.
