... in the dislocation density. Fatigue strength was improved by deformation rate (i.e., rolling speed), which is also due to the increasing dislocation density. Yield stress of the studied specimens followed the same pattern as fatigue strength. Considering the obtained results from the low and high speed, partial...

... conical cavity was chosen due to its simplified analysis. The geometry of truncated conical die cavities is determined by its base diameter (Do), its top diameter (Di) and its height ( H ). A schematic die design is shown in Fig. 1 . The material behavior is mainly expressed by its yield stress σ...
