Summary The microstructure of creep‐tested CM186LC Ni‐base single‐crystal alloy was studied to assess its suitability for use in the gas turbine environment. Creep tests were conducted at 750 °C and at stresses of 560 and 675 MPa up to 11 440 h. The microstructure of fractured and terminated specimens was investigated by light microscopy, scanning electron microscopy and analytical transmission electron microscopy. Microstructural analysis revealed the differences in the microstructure of creep‐tested CM186LC depending on the stress applied during creep at 750 °C.
