English Abstract
This research studies the effect of heat treatment (precipitation hardening) on fatigue life of two aluminum alloys (2024) and (7075).
The alloys samples which used in fatigue tests and mechanical tests are subjected to cold worked before the heat treatment.
The alloy (2024) is hardened by natural aging, while the artificial aging is used to hardening the alloy (7075).
Mechanical tests are performed to determine the mechanical properties such as yield stress, ultimate tensile strength, hardness and endurance limit of the alloys.
In addition to mechanical tests, the microstructure examination and X-ray diffraction inspect are performed to study the variations in microstructure after the heat treatment.
The specimens which used in the tests are divided into two groups according to the type of alloy, type of heat treatment, and shape.
Notched specimens and unmatched specimens are used to perform the tests.
After that, the fatigue tests are performed for different type of specimens.
Then, the equations of fatigue life estimation are determined according to data which is obtained from the fatigue tests and endurance limit is calculated by using these equations for each type of specimens.
