Abstract

Neutron scattering experiments have been carried out with undeformed and creep deformed samples of the superalloy CMSX-4. From the measured constrained misfit data, obtained from different reflecting planes with respect to the external load axis, two strain tensors for horizontal and vertical matrix plates can be extracted.

A careful data analysis is necessary since the technical manufactured single crystals show a mosaic spreading of 0.5° and the wavelength spreading of the incident neutron beam, Δλ/λ is about 410-3 This is in the same range as the unknown constrained misfit quantities δc. A method has been developed which allows a calculated intensity distribution to be fitted to the measured one.
