Popis: | In this study, the investigation of effective stresses of Titanium Grade 5 feedstock material during the continuous forming process has been carried out. The numerical simulation has been carried out through a finite element tool DEFORM-3D. The experimental plan and design have been carried out by using Response Surface Methodology (RSM) on MINTAB platform by considering extrusion wheel velocity and feedstock temperature as main extrusion parameters. Effective-stresses of Ti-6Al-4 V alloy have been investigated to understand the deformation behavior for further more applicability of feedstock material in the modern industrial sector and to keep the shoe and other components of the CONFORM machine safe. It has been found that the effective-stress of feedstock material is high in the biting - deformation region and then gradually decreases towards the flowing direction of the material. It has been observed that as the feedstock temperature increases, the value of effective stresses which occur in other region decreases to some extent. So, the result concludes that increasing extrusion wheel velocity and feedstock temperature of alloy will reduce the shear strength of feedstock material during the continuous forming process. Therefore, the load requirement for deformation can be reduced. Moreover, the wear of extrusion shoe which is one of the most important elements can also be minimized thereby enhancing the life of extrusion shoe material. |
