en “Impact of Grain Reduction on the Behavior of AZ91 Magnesium Alloys During Wear and Corrosion” گروه سرامیک Ceramic Materials and Engineering Research Paper Research Paper Magnesium and the alloys made from the same metal are utilized in the engineering applications such as automotive, marine, and aircraft, among others due to high strength to weight. Nevertheless, the applications of magnesium alloys are currently limited to a certain level due to their poor wear and corrosion properties. Another effective strategy for enhancing these properties involves utilizing the process of equal channel angular extrusion (ECAE), which serves to refine the grain structure, thereby resulting in improved material properties. This paper aims to establish the relationship between grain size reduction and wear and corrosion of AZ91 alloy. The wear performances of both coarse-grained and fine-grain alloy were conducted using L9 orthogonal array of experiments in order to study the effects of control parameters on wear performance. In the study, it has also been identified that through ECAP, the corrosion barrier and wear characteristics of the alloy were enhanced due to fine-grain-structure and the spheroidal precipitation of the second β-phase particles. Further, the influence of these changes on the performance of the AZ91 Mg alloy was assessed using SEM.   AZ91,Equal channel angular press,Wear,Fine grain,Corrosion. 60 71 http://ijmse.iust.ac.ir/browse.php?a_code=A-10-5759-1&slc_lang=en&sid=1 Gajanan M Naik gajananmn.rvitm@rvei.edu.in 1800319475328460020962 1800319475328460020962 No RV Institute of Technology and Management Santhosh Kumar B M santhoshkumarbm@jssateb.ac.in 1800319475328460020963 1800319475328460020963 No Assistant Professor, SJCE, JSS Science and Technology University, Mysuru, Karnataka, India-570006 Shivakumar M M shivakumarmm@bmsce.ac.in 1800319475328460020964 1800319475328460020964 No Department of Mechanical Engineering BMS college of Engineering Bengaluru, Karnataka India-560019 Ramesh S ramesh@rvu.edu.in 1800319475328460020965 1800319475328460020965 Yes School of Computer science and Engineering, RV University Maruthi Prashanth B H bhmprashant@gmail.com 1800319475328460020966 1800319475328460020966 No 4Department of Mechanical Engineering AGMR college of Engineering and Technology, Hubli, Karnataka India-581207 Gajanan Anne6 gajanan.anne@manipal.edu 1800319475328460020967 1800319475328460020967 No Department of Mechanical and Industrial Engineering, Manipal Institute of Technology, Manipal Academy of Higher Education, Karnataka, India-576104
