The analysis of friction effect on equal channel angular pressing (ECAP) process on Aluminium 5052 to homogeneity of strain distribution
In the current study, the effect of friction coefficient on strain distribution and deformation was investigated with the computer simulation providing a better understanding of the material flow mechanism and deformation behavior in the ECAP. The 10×10 mm and 50 mm-long rectangular billet was used...

In the current study, the effect of friction coefficient on strain distribution and deformation was investigated with the computer simulation providing a better understanding of the material flow mechanism and deformation behavior in the ECAP. The 10×10 mm and 50 mm-long rectangular billet was used as the geometry of aluminum material. The geometry of dies is 105° channel angle, 0 mm inner fillet radius, and 5 mm outer fillet radius. The dies were modeled as rigid bodies, and the specimen was assumed as a bilinear hardening model. The effect of friction was investigated with the three-level variation coefficient of friction (0.01; 0.025 and 0.05). Based on the result, it can be shown that the friction affects the strain distribution condition. The friction of 0.05 produced more uniform strain distribution, better homogeneity, and smaller corner gap. The experimental study of modeling results was done with MoS2 lubricant while the strain distribution was verified by the microhardness test. The microhardness distribution test result was similar to strain distribution from modeling. |
