Influence of heat treatment on interface of Cu/Al bimetal composite fabricated by cold rolling
چکیده انگلیسی
A copper/aluminum/copper sandwich clad sheet was fabricated by means of cold rolling process and heat treated with different temperature and time. The Al/Cu interface and its bond strength were investigated by SEM, TEM and peeling test. The results reveal that low temperature heat treatment can improve the morphology of Al/Cu interface and increase its bond strength. However high temperature and long time result in the formation of Al2Cu intermetallic compound layer, which is detrimental to the bond strength, and moreover, small Al2O3 particles precipitate along the Al2Cu and Al interface. When the interlayer along Al/Cu interface grows to a certain thickness, the effect of heat treatment temperature and time become weak. For the present study, the reasonable heat treatment may be 423 K and 20 h.
