摘要
Neutron diffraction measurements of the residual intergranular strains generated by uniaxial plastic deformations of + 5.6 and - 6.0% in samples of Inconel-600 are presented as strain pole-figures for the (111), (002), (220), and (113) reflections of the face-centered cubic structure. The results agree with earlier unusual results obtained for Inconel-600 and also show that the intergranular strains change sign when the sign of the plastic deformation is reversed. The results provide a test of the elasto-plastic self-consistent model with which they are critically compared. Published by Elsevier Science S.A.
