Abstract
Transmission electron microscopy has been used to investigate the dislocation structures produced in single crystals of Al-Al3Ni and Al-Al2Cu eutectics deformed in tension. Matrix dislocation densities in the as-grown eutectics are very high, owing to differential thermal contraction effects. The subsequent deformation behaviour of the eutectic crystals is shown to be controlled by the initial high dislocation density, and a constraint effect due to the presence of closely spaced fibres or lamellae.
