Manufacturing of Bimetal Composites 1060/5083 Composites Via Accumulative Press Bonding

Abstract

In-this-study using accumulative press bonding (APB) process, bimetal AA1060 and AA5083 have been fabricated. The aluminum bars were firstly press bonded and then this process continued up to five pressing steps. In the APB process, the composite samples were preheated at 320°C for 7 min before each pressing step. Mechanical-properties-of the-AA1060-AA5083 composites were appraised in appraisal to AA1060-AA1060 and AA15083-AA5083 accumulative press bonded single alloy MMCs. It was found that both of aluminum alloys deform in a same way in the AA1060-AA5083 composites-up-two-APB steps and then AA5083 layers began to neck. Also, it was found that the average strength of the AA1060-AA5083 composites is more than that of these-two-single-alloy MMCs. Moreover, by using-scanning-electron-microscopy (SEM), the effect of APB steps on the fracture surfaces of bi alloy composites have been investigated.
