تم في هذا البحث دراسة تأثير إضافة النيكل بنسب مختلفة على الخواص الميكانيكية لسبيكة ألمنيوم-نحاس و التي تمت معالجتها بالتعتيق الاصطناعي لفترات زمنية مختلفة و قد تمت دراسة تأثير النيكل على استجابة السبيكة لمعالجة التعتيق الاصطناعي. حيث تمت دراسة تأثير نسبة النيكل في السبيكة على البنية المجهرية و الحجم الحبيبي، و على الخواص الميكانيكية كالقساوة و مقاومة الشد و اجهاد الخضوع و الاستطالة، و قد تبين أن زيادة نسبة النيكل في السبيكة تؤدي لتحسين هذه الخواص إذ حصلنا على أفضل النتائج عندما كانت نسبة النيكل في السبيكة 5%.
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 response 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.

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.
The effect of artificial aging on the revolution of mechanical
properties of aluminum alloy 6063-T5 has been studied. Samples of
aluminum profiles which are formed by extrusion process have
chosen, then studied the effect of artificial aging on th
e hardness
and mechanical properties by applied two aging stages and many
stages comparing to the traditional way which be done in one stage.
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).
In This research a surface hardening process by Ni coating and
subsequent diffusion heat treatments was studied at Al7075 alloy.
Nickel coatings with different thickness were obtained.
