Abstract

Bimetallic parts are widely used in chemical industry, petroleum, heat exchangers, and pressure vessels due to their properties of Bimetallic Workpieces, especially high weight strength, better mechanical properties, and at the same time reducing cost and weight loss compared to single-layer parts. Among the various processes used to produce these components, extrusion is a good choice for the formation of bimetallic parts due to the compressive stress and the possibility of metallurgical bonding. In the current study, the effect of temperature on the production of bimetallic parts in the case of shell copper and core aluminum alloy by extrusion method has been investigated. In this study, the two-layer connection of metal for a 45% thickness reduction the ratio was performed for three temperatures of 200, 300, and 400° C. Mechanical properties were also examined using a uniaxial tension test and a microstructure by using optical microscopy and scanning electron microscopy. The results showed that at the ratio of 45% thickness reduction at 200° C, there was no acceptable connection between the two layers, and after the process and cutting off the workpiece, the two layers did not separate, but a weak connection was established The microscopy images at the temperature of 300° C showed that this temperature was the threshold for the two-layer connection, and finally, at the 400° C, a more suitable connection was obtained in the bimetal parts.
