MECHANICAL AND BONDING PROPERTIES OF BI-METAL Al/Cu BULK COMPOSITES PRODUCED VIA APB TECHNIQUE

Abstract

In this investigation, Al1060 and pure copper are used to fabricate bi-metal Al–Cu composites via accumulative press bonding (APB) process. The Al and Cu bars were press bonded and continued up to five pressing steps. In the APB technique, the composites manufactured were heated at 320∘C for about 8[Formula: see text]min and prior to each forming step. Mechanical properties of these bi-metal composites were assessed in evaluation to Al–Al and Cu–Cu APB processes Metal Matrix Composites (MMCs). It was shown that both Al and Cu deform in the same style in the Al–Cu samples after two steps-APB steps and afterward Cu layers started to neck. Also, it was realized that the average value for the strength of the Al/Cu composites is upper than that of these two MMCs fabricated via one metal. The peeling strength of these products enhanced via the APB steps. Moreover, the effect of APB steps on the fracture and peeling surfaces of bi-metal composites have been investigated by using scanning electron microscopy (SEM).
