in all engineering applications where solid surfaces slide on each other, friction plays an important role. it becomes even more important, particularly in metal forming processes where the two sliding materials are metallic. among forming processes, forging is an important process, because of improving material structure, mechanical properties and reducing production time. an inverse analysis ...

Radial additive friction stir repairing (R-AFSR) assisted by stationary shoulder was put forward in the present study, which can be employed to repair mechanical hole out of dimension tolerance AZ31 magnesium alloy sheet. The results show that has sealed-barrier, heat-sink and extra-forging effects. effect improves microstructure uniformity along zone (SZ) thickness surface appearance repaired ...

The demand for more efficient manufacturing processes has been increasing in the last few years. The cold forging process is presented as a possible solution, because it allows the production of parts with a good surface finish and with good mechanical properties. Nevertheless, the cold forming sequence design is very empirical and it is based on the designer experience. The computational model...
