摘要：

In the present work we investigate the creep behavior of a single crystal superalloys (SX), using precisely oriented miniature tensile creep specimens. We study the single crystal superalloy ERBO/1 (CMSX-4 type) in the temperature range between 1023 and 1323 K. We investigate how creep rates evolve in different stress/temperature regimes when tests are performed in the crystallographic loading directions [001], [110] and [111] and on how minimum creep rates depend on stress and temperature. Special emphasis is placed on the early stages of creep in the low temperature/high stress regime at 1023 K and 800 MPa.
