Abstract
This paper reports new dislocation configurations responsible for cyclic hardening/softening behaviour of a directionally solidified nickel base superalloy after relaxation fatigue tests at 850 degrees C with hold durations of 1 and 5 min. Dislocation interactions in the gamma (gamma)-matrix and the formation of new dislocation configurations during relaxation fatigue (RF) test with 1 min hold duration is responsible for the cyclic hardening behaviour, whereas, the coarsening of gamma prime (gamma')-precipitates are attributed to the cyclic softening behaviour during 5 min hold testing.
