Cooling holes Ni-base superalloy Temperature gradient Thermal stress Thermo-Mechanical Fatigue
It is important to get basic understandings on early stage crack propagation behavior around the cooling holes machined in high temperature hot section components in advanced gas turbine system. For the purpose a new testing system has been developed in this work. By means of the test system the thermo-mechanical fatigue (TMF) crack propagation tests were carried out specifying a directionally solidified Ni-base superalloy specimen in which some cooling holes were introduced in the gauge section part o...
