Deformation and strain analysis for grain refinement of materials processed through equal channel angular pressing

Among the various metal forming forms ECAP is one method in which nano crystalline and ultrafine grain metal and amalgams are formed. This method is used for high strain super plasticity in the material by grain refinement to the nano or submicron level, without changing the dimensions of work piece. In this process metal is forced to pass repeatedly through the specially designed channel die with intersectional channel for different angels. The modeling of the die and the billet was done through SOLIDWORKs 2017 and quantitative analysis was done through ANSYS workbench 15.0 software. The result was compared with practical results for different channel angle and it was observed that the ideal parameters for most extreme homogeneity in strain can be accomplished with channel angle Φ = 90 0 , corner angle Ψ = 15 0 and coefficient of friction μ = 0.25.
