ABSTRACT Material types with different chemical and physical properties are employed by being joined in industrial applications. The major objective is to generate high-performance prochannels by bringing outstanding properties of materials together. Many conventional methods, primarily welding method such as casting, adhesion, rivet weld, and bolts are employed in joining procedures. Among the joining methods, mechanical locking, a novel and ecologically friendly method, stands out as a successful method, particularly when joining dissimilar metal types. Within the scope of this study, the optimization of the channel geometry was performed on the AZ91 mold part, out of AA7075/AZ91 material pairs joined by using the mechanical locking method. The channel design was paid attention to ensure that it do not adversely affect the stress values and facilitates material flow. Fixed joint angle and fixed channel depth were used in accordance with the data received from previous research results and employed in the analysis. The analyses were completed using the finite element method and the Static Structural Module of the Workbench 18.2 version of the ANSYS software. The whole study was carried out on 3D geometric models. As a result, it was determined that the mechanical properties of the samples joined by MLM significantly changed depending on the channel design. The mechanical properties of the joint improved by roughly 3% with the optimal joint design, while the joint design that will facilitate material flow was achieved.
