The effect of notches on high temperature creep behaviour of CMSX-4 superalloy single crystals.
Original language description
This paper deals with the effect of notches on creep strength of the hi-tech high temperature material, CMSX-4 superalloy single crystals. Cylindrical bars of the orientation <001> with circumferential notches were tested at 850 C under constant loads. Two types of notches with different notch geometry and therefore with different notch acuity and different degree of stress triaxiality were used. The notched specimens exhibit a longer creep lifetime than the smooth specimens for the same net-section stress. This can be attributed to the strain constraint caused by the stress triaxiality. Stress-strain analysis of the notched specimens was performed using the general purpose finite element system ANSYS. The creep data of smooth specimens were used as input data. An excellent correlation between the creep lifetime of the notched specimens and the average value of the calculated steady-state creep strain rate was found.
