The Effect of Channel Depth on Joint Quality in Cu/AISI 1040 Materials Joined by Mechanical Locking Method

Abstract

The aim of this study is to investigate a novel and environmentally friendly method that is an alternative to conventional methods in the production of bi-metallic products. Bi-metallic products are obtained by joining materials with different physical and chemical properties. As a result, the desired properties of different materials can be used together. Numerous conventional methods such as welding, casting and pressing are used in the production of bi-metal materials. However, Cu and AISI 1040 steel materials are almost impossible to be joined by conventional production methods. The original value of this study is that these materials can be joined by a new method, the Mechanical Locking Method. In the joining process, a constant speed (1400 rpm), a constant feed rate (16 mm/min) and different channel depths (10, 13, and 15 mm) were used. The effect of the channel depth, one of the physical design parameters, on the joint quality was investigated. The mechanical and microstructural properties of the joint were determined experimentally. In conclusion, it was determined that the Cu/AISI 1040 material pair was successfully joined by using the Mechanical Locking Method and the most suitable channel depth was 10 mm.
