| ABSTRACT |
| The aim of this study is to investigate the change of microstructural properties of AA7075 alloys
after severe plastic deformation. Severe Plastic Deformation is a process used to improve the
properties of the material by creating intense plastic deformations on the material surface. Equal
channel angular compression molding (ECAP) was used for the severe plastic deformation process
in our study. AA7075 alloy samples were primarily prepared for severe plastic deformation
treatment. Then, the microstructural properties of the samples were investigated using various
imaging techniques such as scanning electron microscopy (SEM) and transmission electron
microscopy (TEM).
The research results showed that significant microstructural changes occurred in AA7075 alloys
after the severe plastic deformation process. The SPD process improved the mechanical properties of
the material by transforming the crystalline structures of the material into a fine-grained structure.
In addition, it was observed that deformation lines and pits occurred on the surface of the samples
after the SPD process. It is seen that the SPD treatment increases the mechanical properties of the
material such as strength, hardness and durability. Therefore, this study is an important step towards
the development of the alloy's use in various industries. |
