Importance of Mathematical Modeling (Response Surface Methodology) in Equal Channel Angular Pressing

Sunil Kadiyan, B. S. Dehiya

Abstract


Severe plastic deformation is a technique for producing a deformation. Equal channel angular pressing is one of the unique methods for producing high plastic deformation in Aluminum alloys due to its quality of having the same dimensions after processing. In present work, A die was designed on the basis of a mathematical model generated by RSM. Variation in die geometry and other conditions were represented in present work. ANOVA presented the mathematical model and the best possible die geometry for the maximum deformation. A confirmatory test was performed to check the validity of the model. Aluminum alloys are light in weight and largely used in the automobile and defense sector.
