In this study, severe plastic deformation (SPD) and wear behavior of AA 7075 allosy widely used in aerospace, automotive and defence industries, has been investigated. The equal channel angular pressing (ECAP) process was applied to achieve an ultra-fine grain structure of homogenized AA 7075 materials. Solid particle abrasion behavior was impressed into homogenized and ECAP' ed materials via a variable particle impingement angle (PIA) and acceleration pressure. Microstructure and wear behavior of the tested materials were investigated using scanning electron microscopy (SEM) and a surface profilometer. In the studies conducted, it was observed that an increase in the number of ECAP passes with the effect of SPD, reduced the solid particle wear behavior.
