The squeeze casting of a 2024 Al alloy was carried out to investigate the effect on microsegregation in the alloy of theapplication of pressure followed by diffusion annealing. The experimental results indicate that an optimum appliedpressure followed by an optimum diffusion annealing process can markedly reduce the degree of microsegregation andimprove the mechanical properties to a degree that can approach the level of forged 2024 Al alloy.
