Abstract AR

البحث الحالي يعرض دراسة عملية لمعرفة تأثير القذف بالكريات المعدنية على المواصفات الميكانيكية و الاجهادات المتبقية لسبيكة الألمنيوم ذات الرقم (T351-AA 2024) تحت تأثير زمن القذف SPT.

أظهرت النتائج أن وجود SPT يؤدي إلى تحسين المواصفات الميكانيكية و عمر الكلال لحد قيمة معينة من SPT.

الزمن 15 دقيقة أعطى أعلى قيم للمواصفات الميكانيكية بنسبة 6.7 % لأقصى إجهاد شد و 11.7 % لإجهاد الخضوع.

تم اقتراح معادلة لحساب العلاقة بين SPT مع حد الكلال و الاجهادات المتبقية.

E.L =167.6 (SPT)0.055 σ R.S = 10.755(SPT)0.512σ

Abstract EN

This paper presents an experimental study on the effect of shot peening on mechanical properties and residual stresses of 2024-T351 Aluminum alloy.

Under the effects of shot peening time SPT the results show that the existence of SPT can improve the mechanical properties and fatigue life up to a limit value of SPT.

The 15 minutes SPT gave the highest value of (σu, σy) which is about 6.7 % for (σu) and 11.7 % for (σy).

Empirical equations were proposed to evaluate the SPT with the endurance limit stress and the residual stresses.
