摘要：
The influence of different heat treatments on the microstructure of ordered cuboidal gamma' precipitates in the ZS26 superalloy (wt%: Ni 64, W 11, Co 9, Al 6, Cr 5, Nb 1.5, Ti 1, Mo 1, V 1) was studied by small-angle neutron scattering. The average shape and size of the precipitates were determined by modelling the scattering curves and by fitting them to the measured 2D data. The volume fraction of the precipitates was deduced from the fitted parameters under the assumption of a homogeneous distribution of particles inside the sample.
