摘要：

The nickel based alloys with different Sigma 3 boundary density were achieved by cold-rolling and subsequent annealing treatment. Electron backscattered diffraction analysis showed that the grain size distribution changed with the processing parameters, and the discontinuous Sigma 3 boundary became continuous with the increase of prior deformation level. Furthermore, the Sigma 3 boundary density was found to be manipulated by both grain size distribution and Sigma 3 boundary density per grain which showed an increasing trend with prior deformation level and annealing temperature.
