Abstract<\/strong><\/p>\n

In order to improve the mechanical properties of Al-Si13 alloys various treatments and procedures are recommended such as modification treatment<\/em> of the molten alloy<\/em>.<\/p>\n

In this work, the effects of the modification of the alloy composition owing to the addition of 1 wt.% and 2 wt.% modifier composed of 40 wt.% NaCl and 45 wt.% NaF and 15 wt.% KCl, combined with the application of unidirectional solidification by means of the Bridgman type were studied on the Al-Si13alloy. Microstructural analyses revealed a decrease in the interdendritic spacing(SDAS), in particular owing 2% of the modifier prepared with a reduced pulling traction. The dendrites were preferably oriented along the pulling velocity for fairly low pulling velocity (500 \u03bcm\/s). These microstructural modifications enabled an increase of both the \u00a0hardness (HB) values and the impact toughness.<\/p>\n

Key words: <\/strong>AlSi13 alloy, Modification treatment, Directionally solidification, Bridgman technique, Silicon eutectic.<\/p>\n
