Abstract : It is shown that if partial dislocations are involved in twinning in shock-loaded Cu, these must be intrinsic. The twinning shear was measured directly and found to agree with theory. Recrystallization starts at twin intersections and sweeps along the (incoherent) interfaces before advancing into the matrix. (Author)
