Abstract: This paper addresses the influence of design on the performance of Equal-channel Angular Pressing dies, of which the important geometric parameters are the internal channel angle (Ф) and the curvature radii at this point. The investigation consists of FEM analysis (computational simulation) of the effect on die performance of the independent variation of the outer and inner curvature radii at the channels ́ intersection, plus the corresponding experimental validation (physical simulation). Using a Pb-62%Sn alloy, twelve R-r combinations were simulated and tested, keeping constant the Ф angle. Results indicated the best R-r combinations in terms of equivalent deformation level and homogeneity, together with the optimization of pressing forces.

Abstract: Among the materials employed for orthopedic implants, Ti-6Al-4V is definitely the best choice due to its excellent properties. However, a more intense use is hindered by high cost and the presence of harmful elements, viz. Al and V. A solution can be found in commercially pure Ti, provided its tensile and fatigue properties can be upgraded by some process of Severe Plastic Deformation. In the present work, Grade 2 Ti was submitted to up to four Equal Channel Angular Pressing passes, followed by cold rolling (30 70 and 90% reduction ratio) Hardness and tensile properties were determined, paying attention to the work hardening behavior. Results show that Severe Plastic Deformation gives a 442 MPa increase over the yield strength of annealed Grade 2 Ti (originally 337 MPa), while elongation reached 21%. Best results were obtained with four passes followed by 70% cold rolling reduction. Finally, the microstructural stability was assessed by hardness measurements.
