Sažetak

Due to their excellent corrosion resistance, light weight, hardenability, and high recyclability, aluminum alloys have become a staple in the automotive industry, particularly in the manufacturing of car bodies. However, the Portevin–Le Chatelier (PLC) effect, which manifests in certain aluminum alloys during plastic deformation, poses significant challenges. This phenomenon can lead to undesirable visual and structural defects, thereby limiting the broader application of these alloys in the automotive sector. Understanding the PLC effect is crucial for enhancing the usability of aluminum alloys in vehicle production. This paper deals with the PLC phenomenon, exploring the various parameters that influence its occurrence during plastic processing. By investigating these factors, the aim is to provide a better insight on this phenomenon.
