Abstract
The behaviour of slip lines, on work-hardened and annealed surfaces of aluminium crystals, during stress reversal, has been examined by optical microscopy and multiple-beam interferometry. Strains were kept to less than a few tenths of 1% during any one half-cycle. In all cases it has been found that there is no obvious relationship between slip lines formed during tension and those formed during subsequent compression. In general a slip line is unaffected by a reversal of the stress up to a value of twice the initial, forward stress. A qualitative explanation in terms of internal stresses in the as-grown crystals is given.Keywords
