![]() Moreover, wear resistance was improved with increased ECAP passes. The precipitation of the nano particles were the major reasons for achieving high strength. The author found high dislocation density, grain refinement up to 46 nm. 13 processed AA 7075 using ECAP process at room temperature. 10– 12 Numerous studies have been done to evaluate the wear resistance of the SPD processed materials with the aim to know the potential of the SPD processed material for its use in as clutches in automobile, micro devices, bio-material application and aerospace industries. Generally, materials may require minimum wear rate in various application for example- gear, cam, piston cylinder. The sliding surfaces can have more than one of these wear mechanisms. There are various wear mechanisms which may include abrasion, adhesion, corrosion, fatigue and fretting. Wear resistance is an important property for those elements which have relative motion to each other such that reciprocating motion of piston, rotating motion of bearing etc. In this study, the Vickers micro-hardness, X-ray diffraction analysis, optical microstructural, energy dispersive X-ray spectroscopy analysis (EDS), tensile test, and scanning electron microscopy (SEM) were performed on broken tensile specimens and worn surface of the wear pin. The mechanical properties of Al alloy enhance with increased MAC pass. ![]() The alloy processed by MAC is harder and stronger than the zero MAC pass alloy. After six passes, average grain size was observed to reduce by up to 2.3 µm. The coefficient of regression R 2 was 0.9621, demonstrating the constructed model’s acceptable accuracy. To investigate the impact of various factors and how they interact with one another on wear, surface plots, contour plots, and mean effects plots were developed. The Face Centered Central Composite Design (FCCD) method was made up of three factors, each with three levels. Optical microscopy images were used to detect microstructural changes in the 7075 Al alloy after MAC processing. This study examines the influence of multi-axial Compression (MAC) on the wear attributes of 7075 Al alloy and optimize the dry sliding wear parameters using the response surface methodology (RSM).
