Notch effects on creep behaviour of CMSX-4 superalloy single crystals.
Original language description
Smooth and notched specimens of CMSX-4 superalloy single crystals of orientations <001>, <011> and <111> were creep tested at 850 C. For the same net-section stress the notched specimens exhibit a longer lifetime than the smooth specimens. Stress-strainanalysis of notched specimens was performed by an elastic-plastic FEM procedure; the creep data of smooth specimens were used as input data. An excellent correlation was found between the lifetime of the notched specimens and the average value of the calculated steady-state creep strain rate. For all orientations the life curves of this type were found to be identical with the life curves for smooth specimens expressed in terms lifetime vs. steady state creep rate. Thus a modified Monkman-Grant relationship is valid both for smooth and notched specimens.
