## Abstract A multiβscale model is used to simulate columnar dendritic growth in TIG (tungsten inertβgas) weld molten pool of AlβCu alloy. The grain morphologies at the edge of the weld pool are studied. The simulated results indicate that the average primary dendrite spacing changes during the sol
Observations have been made on coarsening of O-&Al2 precipitates at the surface of AI-G alloys. One specific area was examined over extended periods so that dissolution and growth of individual precipitates could be followed. It was found that nearly all precipitates shrank on ageing, even those lar
