تأثير عناصر السبك و درجة الحرارة على متانة الصدمة للسبائك (المنيوم- خارصين-مغنسيوم)‎

Abstract EN

(Al – Zn – Mg) alloys are widely used in aerospace applications, for their good mechanical and physical properties.

The present research represents a study and comparison of impact toughness of four ternary alloys (Al – Zn – Mg) with two binary alloys (Al – Zn) and one commercially pure Aluminum at seven different temperatures (-5, 0 , 25 , 100 , 200 , 300 , 400 Co) in order to evaluate the role alloying elements and the temperature on toughness .

The findings of the present research yield a tangible effect of alloying elements in reducing the toughness more than temperatures .
