    Effect of notches on high temperature fatigue/creep behaviour of CMSX-4 single crystals.

  • Original language description

    Effect of notches on high temperature fatigue/creep strength of CMSX-4 single crystals has been investigated. Cylindrical bars of the orientation <001> with circumferential notches were tested at 850 C under constant loads both without and with superimposed high frequency cyclic loads. Under creep conditions, the notched specimens exhibit a longer creep lifetime than the smooth specimens for the same net-section stress. Stress-strain analysis of the notched specimens subjected to constant loads was performed by an elastic-plastic FEM procedure; the experimentally determined creep data of smooth specimens were used as input data. An excellent correlation was found between the creep lifetime of the notched specimens and the average value of the calculated steady-state creep strain rate. The creep life curves of notched specimens were found to be identical with the creep life curves of smooth specimens when expressed in terms of Monkman-Grant diagram.
