## 3 Results  
We initially consider two parts of profiles shown in Figure 5a,b. From these parts will be adjusted the TRZ configurations and will be studied, from the planes of symmetry, a quarter of each profile, considering the situation of a piece with symmetric configuration (Figures 6 and 7). Figure 5: (a) Pieza 1; (b) Pieza 2. Figure 6: 3 TRZ part configuration 1. Each one of the three TRZ of the selected modules in configuration 1 has the width of 4, 4, and 3, respectively (counted from left to right from the vertical plane of symmetry), with an initial module height of 6. For the piece with configuration 2, the TRZ are 4, 3, and 5 in width, respectively, keeping the same height for the initial TRZ. Once established the configurations of the two quarters of part selected, both configurations are combined as an only part, generating the profile shown in the next figure (Figure 8). As shown, the yield plane of the material derived from the forging process is coincident with the symmetry plane in the initial configurations. In this new configuration will be necessary to calculate the position of the vertical plane from which the material flows in opposite directions. This position will be calculated determining the position of the center of mass of the entire profile on the \(X\)-axis, taking the point \(A\) as origin (Figure 9). In the current configuration, the \(X\) dimension is 11.222. Figure 8: New configuration without horizontal symmetry (ws). Figure 7: 3 TRZ part configuration 2.

Table 3: \(P/2k\) modules values and total values: configuration 1 ws. It is interesting to note the new extra module in the configuration 2 ws, which comes from the modification of the new yield plane position. Based on the results obtained, it can be observed the influence of the variation of the width of the additional extra module added in configuration 2 ws. This module has a very small width, so for module 1, in this configuration, 2 ws is highly distorted and could affect the result of the total \(P/2k\) ratio, increasing it significantly. However, this influence is slightly compensated by the reduced value of the area of the aforementioned module and, therefore, its influence is reduced (Figure 12b, Table 4). It can be seen how the value of the \(P/2k\) ratio decreases in the new configurations with the appearance of the new flow plane and the extra module. For example, for a reduction in height up to the value of 6, the values of these relationships in the initial configuration 1 and 2 are 2.166 and 2.346, respectively (Tables 1 and 2), while, with the new redistribution and appearance of a fourth module, in configuration 2 ws the resulting values are 2.053 and 2.259 (Tables 3 and 4), with reductions of 0.113 and 0.087 between the initial and final values of our analysis.
