| 1 | Effect of equal channel angular pressing on AZ31 wrought magnesium alloys显示文摘AZ31 wrought magnesium alloys are light weight materials which play an important role in order to reduces the environmental burdens in modern society because of its high strength to weight ratio,corrosion resistance,and stiffness and machinability.Applications of this material are mainly in structural component i.e.,in constructions,automobile,aerospace,electronics and marine industries.In the present work,the microstructure characterization of the AZ31 alloys up to four ECAP passes at temperature of 573 K was observed for route Bc.Average grain size of the material was reduced from 31.8μm to 8μm after four ECAP passes.Mechanical properties of the alloy improved with increase in number of ECAP passes.Moreover,X-ray diffraction analysis was carried out for as received and ECAP processed material. | Avvari Muralidhar S.Narendranath H.Shivananda Nayaka | 2013 | Journal of Magnesium and Alloys2013，1，4： | 14 |
| 2 | Influence of Route-R on wrought magnesium AZ61 alloy mechanical properties through equal channel angular pressing显示文摘A new fundamental route entitled‘Route-R’is introduced to refine the grains in the material through Equal Channel Angular Pressing(ECAP)process.In route R,specimen is inverted to the original position in each ECAP pass.In the present work,AZ61 alloy is processed using ECAP process for three different fundamental routes mainly route A,route Bc,and route R.ECAP experiment is carried out on AZ61 alloy at lower temperature of 483 K up to two passes.Microstructural characterization is evaluated on unECAPed and ECAPed specimens for three routes.Average 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 respectively.Vickers microhardness of the alloy is found to be 60 HV for as received material.This microhardness of the alloy is increased to 71 HV,72 HV,and 74 HV for route A,route Bc,and route R respectively.Mechanical 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 Bc.Tensile fracture topography of the specimen is analyzed using three different routes for two passes. | Muralidhar Avvari S.Narendranath | 2014 | Journal of Magnesium and Alloys2014，2，2： | 3 |
