N2 - This paper presents an investigation on bending forces and hardness properties of Ti6Al4V alloy sheets processed by constrained bending and straightening (CBS) severe plastic deformation (SPD) technique. CBS was proposed as a continuous SPD process of metals enhanced with homogeneous mechanical properties such as strain and hardness. A physical model for the CBS process was designed and fabricated. Ti6Al4V alloy samples were annealed for stress relief and ductility improvement. Alloy samples were then subjected to CBS process at 20, 10 and 5 mm feed lengths for 1 and 2-passes. Values of bending forces and micro-hardness on samples were determined. Results showed that magnitude and homogeneity of induced strain at 5 mm feed were higher than those at 20 and 10 mm feeds. The maximum average values of bending force and hardness were observed at 10 mm feed and 2-pass as 18296 N and 377.8 HV respectively. The hardness increased by 16.3% over that of annealed samples.
