AB  - In general, continuous drive friction welding (CDFW) of two metals 
may produce three typical regions from a weld interface towards an unaf-
fected base metal: (i) fully deformed or dynamically recrystallized (DRX) 
region, (ii) partially deformed region or thermo-mechanically affected 
zone (TMAZ), and (iii) undeformed region or heat affected zone (HAZ). 
In past studies, it has been shown that different CDFW parameters may 
differently affect the size and structural properties of these regions. Re-
garding the Al/Cu bimetal joints, past studies have also indicated that the 
self- and inter-diffusion of Al and Cu along the short-circuits (dislocations 
and/or grain boundaries) is the mechanism which probably controls the 
growth of detrimental AlxCuy intermetallics at the Al/Cu interface when 
the temperatures are lower than 350°C. Considering the previous and that 
the permissible operating temperature in Al/Cu and other electrical con-
nections is generally between 100 and 150°C, as well as that the structural 
changes in DRX, TMAZ, and HAZ regions are expected to be slower at 
these operating conditions, it is reasonable to assume that the growth kinet-
ics of AlxCuy intermetallics under these conditions might be different in 
the cases of Al/Cu joints produced with different CDFW parameters and/or 
in the cases of post-weld heat treated Al/Cu joints. The aim of the present 
study was to evaluate the effects of different CDFW parameters and post-
weld heat treatment on the formation of AlxCuy intermetallics on the Al/Cu 

 

interfaces of produced joints when they were submitted to long-term and 
low temperature annealing (similar to mentioned operating conditions). 
Structural properties were analyzed be using the light microscopy and 
scanning electron microscopy.

AB  - The objective of this research is to consider the effects of certain parameters of the friction-welding process on the morphology of an aluminum/copper joint. The effect of the following parameters was monitored: the operating time, the operating pressure, the forging time and the forging pressure. The speed was constant during the binding process and reached 1500 min(-1). The preparation of the welding materials was performed in accordance with the industrial production conditions. With the SEM-EDS analysis, it was found that the morphology of the Al/Cu interface slightly changes when we change the distance from the rotation axis, irrespective of the combination of the friction-welding parameters. Apart from this, the joined effects of the operating pressure of 48 MPa and the forging pressure of 160 MPa caused a morphological change of the Al/Cu interface, while the forging time at the moment of the combined pressurizing effect significantly influenced the modification of the Al/Cu interface shape within a very narrow time interval of only a few seconds.
