EXPERIMENTAL AND NUMERICAL INVESTIGATION OF THE FRICTIONAL FORCES IN EQUAL CHANNEL ANGULAR PRESSING
نویسندگان
چکیده
The main limitation of the Equal Channel Angular Pressing (ECAP) is very high required punching force for pushing metallic sample to next channel. Frictional forces in ECAP process are responsible force. participation exit and entrance channels total friction has not been studied experimentally hitherto. Through current study, two dies (1) with (normal die) (2) only one channel (the was missed) were manufactured. Three-dimensional finite element analysis conducted. effect on force, geometry, grain refinement rate investigated numerically. According results, a considerable amount minimum process. comparisons showed that, trend results from experimental investigations good agreement numerical analysis.

Equal channel angular pressing (ECAP) is carried out using two different configurations for the exit channel of the ECAP die, i.e., relieved and choked, with angles of 0.2 °. It is found that using a die with relieved exit channel, the sample was extruded for 6 passes with no surface cracks and an average cell size of 727 nm and a fraction of high angle grain boundaries of 54 % were achieved. M...

Equal channel angular rolling (ECAR) process is one of the methods that have been used to make ultra-fine materials by imposing severe plastic deformation. After repeating the process several times, a large effective strain is applied to the sample that can cause decreasing the grain size and improving the mechanical and physical properties of the metal. In this study, thermal conductivity of t...
