في هذا البحث تم تحضير عينات من سبيكة الألمنيوم 6061 ، و بعد التحقق من تركيبها الكيميائي أجري عليها معالجة حرارية انحلالية عند الدرجة 530°C, و أتبع ذلك بسقاية جزء من العينات بالماء، و الجزء الآخر بالزيت، و من ثم إجراء التعتيق الصناعي على العينات المسقاة بتسخين العينات حتى الدرجة 160°C, وأزمان التعتيق المختارة (h 1,3,5)، و بذلك أصبح لدينا ستة نماذج من العينات و التي تختلف عن بعضها البعض بشروط المعالجة الحرارية، بالإضافة إلى العينة الأساس.
In this research, specimens of aluminum alloy 6061 were received, and chemical composition was investigated. After that solution heat treatment was applied on it at 530°C, a section of these specimens was quenched in water and anther quenched in oil, and two sections were aged at 160°C for times (1,3,5 h), and thus obtained six samples differ in condition of heat treatment in addition to as received specimen.

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 .
