Abstract AR

تم إجراء مجاميع من فحوصات الكلال ثابتة و متغيرة تحت تأثير القذف بالكريات المعدنية لسبيكتين من الألمنيوم 2024 و 5052.

تم فحص ثلاثة عينات غير مقذوفة لكل سبييكة تحت مستويات إجهاد واطئ-عالي (120-280 MPa) لسبيكة 2024 و (40-90 MPa) لسبيكة 5052 تحت درجة حرارة الغرفة و نسبة إجهاد R = -1.

فحصت العينات الباقية بأزمان مختلفة من القذف قبل الفتح الكلال التراكمي.

بينت النتائج أنه كلما زاد زمن القذف تحسن عمر الكلال التراكمي و للسبيكة 2024 لكن عند أعلى من 10 دقائق فإن العمر سيقل بينما لسبيكة 5052 فإن عمر الكلال زاد زمن القذف.

Abstract EN

A series of constant and cumulative fatigue tests under the effect of shot peening were conducted for two aluminum alloys 2024 and 5052.

Three unpeed specimens were tested for each alloy under low-high stress levels (120-280 MPa) for 2024 aluminum alloy and (40-90 MPa) for 5052 aluminum alloy at room temperature and stress ratio R = -1.

Other specimens were exposed to shot peening with different blasting time before the cumulative fatigue testing.

It is found for 2024 Al alloy that as the shot peening time increases the cumulative fatigue life is improved but above 10 min.

the life is reduced.

For 5052 Al alloy the cumulative fatigue life is reduced as shot peening time increases.
