Effect of orientation on the plastic deformation of aluminum single crystals and bicrystals
Tóm tắt
Tensile stress-strain curves are reported for aluminum single and bicrystal specimens. Isoaxial bicrystal specimens were used with one crystal rotated 45° about the stress axis with respect to the other. The axial orientations were chosen so that one, two, four, six, or eight slip systems were initially equally favored. The 45° grain boundary did not raise the stress-strain curve of the bicrystal above that of the corresponding single crystal if two or more slip planes were initially equally favored.
