Abstract:

In this study accumulative roll bonding (ARB) process up to 8 Cycles (equivalent strain of 6.4) at ambient temperature was used in order to improve the mechanical properties of Commercial purity titanium (CP-Ti).Several experiment has been done and Mechanical properties of specimen has been discussed. For investigating optical microscope punching and hardness test were utilized. This is the first study on shear strength of CP-Ti formed by the ARB process. In this study Yield Shear Strength (YSS), Ultimate Shear Strength (USS), elongation, punching energy and hardness were investigated. Results of experiment report that as the number of the ARB process increased, the shear strength increased but after that certain cycle YSS and USS gradually decreased. As well as increasing numbers of ARB cycles, elongation decreased. Result reported that the shear strength of specimen reached to maximum value at certain cycle and afterward due to grain recovery and specimen fracture, it decreased. Experiments indicate that maximum hardness’s and shear strength were obtained in cycle 4 and 6respectively. Furthermore specimen fracture after 8 cycles ARB processing was observed.
