摘要
The thermal conditions on the top surface of an Al-4wt.%Cu alloy billet during spray forming have been monitored using an infrared thermal imaging camera. The thermal history of the billet top surface on the axis of the spray plume has been correlated with through-thickness measurements of equiaxed grain size, porosity and segregation. Transmission electron microscopy shows that a high dislocation density in the as-sprayed billet may be relieved by subsequent heat treatment, which also causes precipitation of theta' from the alpha-Al matrix.
