Sažetak
While designing the machine element there is great emphasis on the material selection. The selected material must meet several criteria that will make the production process as economical and simpler as possible, while maintaining its properties, from start of processing to the final product. As it often happens that the material is exposed to the heat during the processing, it is important to know the potential negative influence of heat on the properties, respectively the microstructure of the material. In this paper, the influence of heat input by the TIG heating process, for the purpose of straightening the aluminium sheets, on the microstructure of the AlMg4.5Mn0.7 alloy was analyzed. The analysis of the TIG tool path was performed with an optical metallographic microscope and scanning electron microscope with EDS to describe certain constituents of interest. The microhardness test was performed at the location of the heat affected zone and its vicinity. For comparison and a better understanding of the influence of heat on the microstructure, each sample was exposed to different parameters in the production process.
