Abstract
Experiments on polycrystalline aluminium show that the cyclic grain boundary migration observed in high temperature fatigue leads ultimately to the development of the orthogonal (diamond) grain configuration. Angular measurements demonstrate that the grain boundaries migrate so that a large proportion (∼ 25%) lies in the angular range of 40 to 50° to the stress axis. Grain growth may occur during the migration process by the elimination of some small grains, although other small grains may increase in size when migration occurs in an outwards direction. Migration is initially rapid, but the rate of migration decreases after large numbers of fatigue cycles. As the rate of migration slows down, the grains become divided into subgrains, and the subgrain boundaries tend also to exhibit an orthogonal configuration.
