Munich: Carl Hanser Verlag, v. 38, n. 2, p. 74-87, 2001.0032-678Xhttp://hdl.handle.net/11449/9337The effects of heat treatment on morphologies and microstructures of Al 2024 and Al 7050 alloys, used as aircraft components, were studied by metallographic techniques. Light microscopy (LM) and quantitative image analysis were used to characterize the precipitate dispersion and morphology for these alloys. The application of the scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) combined techniques for studying these multiphase systems makes it possible to distinguish and quantify the different phases in the surface structure. Xray diffraction also permitted a qualitative comparison of the structures before and after heat treatments.74-87engArtigoWOS:000169916200002Acesso restrito8799191078451467753909726048937507783483005487970000-0001-7897-1905
