【 摘 要 】

There is a wide range of applications of aluminium alloys that contain manganese alloying element. This is mainly due to its good durability, corrosion resistance and cost effectiveness. The biggest proportion of manganese alloying element is in solid solution during the casting process and solidification. Moreover the remaining manganese content can be found also in the casted aluminium in precipitation form. Because of high production volume it is essential to optimise the production process in every respect to assure more economical production. Our experiment focused on one of the most important production steps of rolled products that is hot rolling. During hot forming the plastic deformation and the softening processes takes place in parallel in a complex system. In our experiment we carried out physical simulation with Gleeble thermomechanical simulator. Three aluminium-manganese alloys were compared with different chemical compositions. We applied hot compression tests and then we studied the measurement results.
