摘要：

High-resolution neutron diffraction measurements of the lattice parameter mismatch between the gamma and gamma' phases of CMSX-2 superalloy are reported. Although the existence of a distribution around the lattice parameter value of each phase makes the interpretation difficult, the temperature dependence of the lattice mismatch has been deduced from room temperature to 1300-degrees-C, taking into account the tetragonal distortion of the gamma' phase. Some implications of the measurement for the behaviour of the superalloy are discussed.
