The cyclic stress-strain behavior of the single crystal nickel-base superalloy Mar-M has been investigated at ambient temperature and °C under constant strain rate cycling at 10 −2 and 10 −3 /s. At ambient temperature, the cyclic stress-strain curve exhibits a clear strain rate independent plateau regime similar to that observed for f.c.c.
