This article describes the influences of cooling speed and head treatment on the microstructure and mechanical properties of aluminium alloy AlSi7Mg0,6 (trade description – Anticorodal 72). Results of tensile test (strength, yield strength, ductility, etc. ) to both method heat processing (T6 and T 64).

The mechanical properties of parts prepared by casting are dependent mainly on their microstructure. Grains size, size of dendrites and dimensions, shape and quantity of structural defects has important influence on final mechanical properties of these parts. Image analysis is an appropriate tool which can be use for qualitatively and quantitatively materials microstructure characterization [1,2]. The aim of this study was use an image analysis (Olympus AnalySIS Five) to evaluation of cooling speed influence on aluminium alloy AlSi7Mg0,6 (trade description – Anticorodal 72 [3]) microstructure. Structural parameters (DAS and porosity) were obtained by this method.
