Corrosion behaviour of Al/Al3Ti and Al/Al3Zr functionally graded materials prod...
Ferreira, S. C.; Rocha, L. A.; Ariza, E.; Sequeira, P. D.; Watanabe, Yoshimi; Fernandes, J.C.S.Intermetallic particles, Al3Ti and Al3Zr were formed in Al–5mass%Ti and Al–5mass%Zr alloys, respectively, by centrifugal casting, in order to create functionally graded materials (FGMs). At present, no information is available on the influence of the amount of intermetallics on the electrochemical properties of these alloys. In this paper, the corrosion resistance of Al/Al3Ti and Al/Al3Zr FGMs was investigated...
Particle distribution and orientation in Al-Al3Zr and Al-Al3Ti FGMs produced by...
Sequeira, P. D.; Watanabe, Y.; Rocha, L. A.Al-Al3Zr and Al-Al3Ti functionally graded materials (FGMs) were produced by a centrifugal method from Al-5wt% Zr and Al-5wt% Ti alloys, respectively. Applied centrifugal forces were 30, 60 and 120G (units of gravity). Microstructural characterization was performed to evaluate the intermetallic particles’ distribution and orientation. Knoop hardness tests were carried out, with the indenter’s long diameter norma...
Aluminum matrix texture and particle characterization in Al-Al3Ti FGMs produced...
Sequeira, P. D.; Watanabe, Y.; Rocha, L. A.The centrifugal solid-particle method has proved to be effective in producing functionally graded materials (FGMs). In this study, Al-Al3Ti FGMs, were produced by this centrifugal method, from an Al-5 wt % Ti master alloy. Applied centrifugal forces were 30, 60 and 120G (units of gravity). Samples from the outer surface of each specimen were cut and aluminum matrix texture analyzed by Schulz reflection method. ...
