Description/Abstract

DSC curves of the quenched monolithic 8090 alloy and the 8090 MMC have been used to obtain values for the heats of formation of GPB zones, delta' and S phase. Using these ∆H values and a correction for overlap of effects, the DSC curves of the aged alloys have been interpreted in terms of amounts of precipitates present. The presented interpretations are consistent with previous microstructural investigations. The solvus of GPB zones and of S phase in 8090 alloys has been obtained. Significant amounts of GPB zones are formed in the monolithic alloy, whilst the addition of SiC particles greatly reduces the amount of GPB zones formed.
