Research summary
في هذا البحث، تم دراسة تأثير المعالجة الحرارية على الخواص الميكانيكية وسلوك الاهتراء لسبيكة الألمنيوم 6061. تم تحضير عينات من السبيكة وإجراء معالجة حرارية انحلالية عند درجة حرارة 530°C، تلتها عملية سقاية بالماء والزيت. بعد ذلك، تم تعتيق العينات عند درجة حرارة 160°C لأزمنة مختلفة (1، 3، 5 ساعات). تم إجراء اختبارات ميكانيكية (شد ستاتيكي، قساوة) واختبار مقاومة الاهتراء على كل نموذج، بالإضافة إلى فحص البنى المجهرية. أظهرت النتائج أن زيادة زمن التعتيق تؤدي إلى زيادة مقاومة الاهتراء، بينما تزداد الخواص الميكانيكية حتى زمن تعتيق ثلاث ساعات ثم تعود للانخفاض. تم التوصل إلى أن السقاية بالماء تعطي مقاومة شد وقساوة أعلى مقارنة بالسقاية بالزيت، ولكن السقاية بالزيت تعطي استطالة شد نسبية أعلى.
Critical review
دراسة نقدية: يعد هذا البحث ذو أهمية كبيرة في مجال دراسة تأثير المعالجة الحرارية على سبائك الألمنيوم، وخاصة سبيكة 6061. ومع ذلك، يمكن تقديم بعض الملاحظات النقدية لتحسين البحث. أولاً، كان من الأفضل توضيح المزيد من التفاصيل حول كيفية اختيار أزمنة التعتيق المختلفة وتأثيرها على النتائج بشكل أكثر دقة. ثانياً، يمكن أن يكون من المفيد إجراء مقارنات مع نتائج دراسات سابقة لتأكيد النتائج الحالية. ثالثاً، كان من الممكن توسيع نطاق الدراسة لتشمل اختبارات إضافية مثل اختبارات الصدم أو التعب لتحليل أعمق للخواص الميكانيكية. وأخيراً، يمكن تحسين العرض البصري للبيانات من خلال استخدام رسوم بيانية أكثر توضيحاً وتفصيلاً.

In this research the effect of Nickel addition by various percentages on the mechanical properties of Aluminum-Copper alloy was studied. After adding Nickel the alloys was artificially aged for different times, and the effect of Nickel on the re sponse of alloy to precipitation hardening was studied. Where the effect of Nickel on the microscope structure was studied, and on the mechanical properties as hardness, tensile strength, yield strength and elongation. The results showed that the increase of Nickel improve this properties, where the highest values were obtained when the Nickel's percentage was 5% Wt.
A new group of Z n - Al alloys suitable for casting was developed in the late sixties, These alloys are ZA - 8 , ZA - 12 and ZA – 27, where the numbers represent the approximate percentage of aluminum in the alloy. These alloys compete with cast iro n and copper alloys and aluminum alloys. ZA – 27 alloy is characterized by the biggest strength and lowest density alloy from the rest of ZA alloys. It has good physical and mechanical properties (good strength, good cast ability, ease of machining, good wear properties and high corrosion resistance). This research is aimed to study the effect of heat treatment on mechanical properties as well as to improve the wear properties of ZA-27alloy. Heat treatment of type T4 was applied on ZA-27 alloy (This treatment was done by heating the alloy to a temperature equal to 370 oC for a period of 3 or 5 hours and then immersion in water followed by natural aging for 30 days). Wear testing has been made by using dry sliding test of pin samples on the disk - ZA – 27 alloy after casting without any treatment and wear tests were performed on heat treated ZA – 27 alloy samples. The microstructure of the alloy after casting and after heat treatment was examined and the effect of the microstructure on the wear behavior was studied. The hardness and tensile strength of heat treated samples were reduced while elongation was increased compared with alloy after casting. The rate of decrease of hardness was equal to 34.7 %, which is consistent with solutionizing period. On the contrary, the increase in the solutionizing period decreases strength and increases elongation. The study shows also that the heat treated samples have achieved a significant improvement on wear properties compared to the samples after casting without heat treatment
Because of large industrial development which the world has seen in all fields. scientists and researchers aim to produce new materials that having special engineering properties with low economic cost as fit multiple industrial application and us es. So in This present article We try to prepare composite materials based on aluminum alloy (6663) and reinforcement it by different particles having size of micron of Alumina and silicon carbide particles are added in specific weight parentage by stir casting technique to obtain Aluminum Which having the improving mechanical properties
In this work, the processing of aluminum alloys - copper, which added amounts of copper to aluminum in different parentages (2.5- 4-4.5%) so as not to exceed the limit of saturation Aluminum 6 %( copper).
This research aims to study the effect of adding alloying elements and heat treatment of Zinc metal on solar energy absorbing , nine alloys ingots were manufactured by changing the percentages of added Aluminum and Copper on the pure Zinc, and thes e ratios of Aluminum were : (10% , 20% , 30% , 40 % , 50%) to demonstrate the effect of adding Aluminum to Zinc metal on solar energy absorbing , and ratios of copper were : (20% , 40%) , as well as we prepare two pure zinc samples with 99.2% of purity , one was rapidly cooled and the other slowly cooled , to demonstrate the effect of heat treatment on solar energy absorbing . In order to measure the solar energy absorbing for prepared samples , we manufactured a device depends on the methods of heat exchange between solar radiation and the surface exposed to radiation . The obtained results showed that adding Aluminum and Copper to the pure Zinc caused a decrease in solar energy absorbing . As well as increasing the percentages of adding Aluminum and Copper to the pure Zinc caused a gradually decrease in solar energy absorbing . comparing the absorbing of pure zinc samples, one was rapidly cooled and the other slowly cooled , the results showed that the sample was rapidly cooled was better than the sample slowly cooled on solar energy absorbing .
