Among alloys of non-ferrous metals, aluminum alloys have found their broadest application in foundry industry. Silumins are widely used in automotive, aviation and shipbuilding industries; as having specific gravity nearly three times lower than specific gravity of cast iron. The silumins can be characterized by high mechanical properties. To upgrade mechanical properties of a castings made from silumins one makes use of heat treatment, what leads to change of their structure and advantageously affects on mechanical properties of the silumins. In the paper are presented test results concerning effect of dispersion hardening on change of tensile strength of EN AB-48000 silumin modified with strontium. Investigated alloy was melted in electric resistance furnace. Temperature ranges of solution heat treatment and ageing heat treatment were selected on base of curves from ATD method, recorded for refined alloy and for modified alloy. The heat treatment resulted in change of Rm tensile strength, while performed investigations have enabled determination of temperatures and durations of solution heat treatment and ageing heat treatment, which precondition obtainment of the best tensile strength Rm of the investigated alloy.
