主　　题：ECAP Routes AZ61 alloy Microstructure Properties 

摘      要：A new fundamental route entitled‘Route-R’is introduced to refine the grains in the material through Equal Channel Angular Pressing(ECAP)*** route R,specimen is inverted to the original position in each ECAP *** the present work,AZ61 alloy is processed using ECAP process for three different fundamental routes mainly route A,route Bc,and route *** experiment is carried out on AZ61 alloy at lower temperature of 483 K up to two *** characterization is evaluated on unECAPed and ECAPed specimens for three *** grain size of the alloy is to be reduced from 66μm to 16μm,14.1μm and 10μm for route A routes Bc,and route R *** microhardness of the alloy is found to be 60 HV for as received *** microhardness of the alloy is increased to 71 HV,72 HV,and 74 HV for route A,route Bc,and route R *** properties of the AZ61 alloy are observed to be route R is providing maximum YS,UTS,and percentage elongation than other route A and route *** fracture topography of the specimen is analyzed using three different routes for two passes.
