Precipitation processes occurring during the heat treatment of the silumins containing additives of Cu and/or Mg have effect on improvement of mechanical properties of the material, while choice of parameters of solutioning and ageing treatments belongs to objectives of research work performed by a number of authors. Shortened heat treatment, which is presented in the paper assures suitable mechanical properties (Rm), and simultaneously doesn’t cause any increase of production costs of a given component due to long lasting operations of the solutioning and ageing. Results of the research concern effects of the solutioning and ageing parameters on the Rm tensile strength presented in form of the second degree polynomial and illustrated in spatial diagrams. Performed shortened heat treatment results in considerable increase of the Rm tensile strength of the 320.0 alloy as early as after 1 hour of the solutioning and 2 hours of the ageing performed in suitable.}, type={Artykuły / Articles}, title={Effect of Shortened Heat Treatment on Change of the Rm Tensile Strength of the 320.0 Aluminum Alloy}, URL={http://journals.pan.pl/Content/88423/PDF/13_paper.pdf}, doi={10.1515/afe-2015-0013}, keywords={Aluminum alloys, ATD, Heat treatment, Tensile strength}, }
