EFFECT OF THE NUMBER OF THE PASSES ON THE MECHANICAL BEHAVIOUR OF ALUMINUM ALLOY PROCESSED USING EQUAL CHANNEL ANGULAR PRESSING (ECAP)

Abstract

One of the most important industrial processes used in the production of nanomaterials is the ECAP process. Whereby, nanomaterials are produced in relatively large sizes. In this research, the effect of the number of passes on the mechanical behavior of the engineering material was studied. Where the upsetting test was carried out on samples taken from a metal produced by the ECAP process, then the yield stress, maximum stress, and strain values were determined, as well as the Tresca energy fracture criterion was used, and the results were analyzed and converted into graphic relations. From the results, it was found that these values are highly dependent on the number and type of passes.Keywords: ECAP, Aluminum Alloy, Upsetting Test, Mechanical Properties, Anisotropic.
