Paper Title:
Microstructure and Mechanical Properties of Titanium Severely Strained by Means of Friction Roll Processing
  Abstract

Severe strain has been introduced to commercially purity (CP) titanium samples by means of friction roll processing (FRP), which represents an alternative severe plastic deformation technique by inducing shear strain. FRP has an excellent possibility of controlling surface microstructure combining with subsequent annealing. The resultant microstructure refinement and texture evolution has been investigated. Hardness of sample was measured to compare mechanical properties of samples before and after FRPed. Parameters including the different indentations given to the sample and sample feeding speed were experimentally conducted to find the optimum condition for investigating effect on microstructure evolution. After subsequent annealing, the evolutions of microstructure and texture were observed by field emission scanning electron microscopy (FESEM) and analyzed by scanning electron microscopy/ electron back scatter diffraction pattern (SEM/EBSP) technique. Transverse texture was found to be the preferred orientation existing in the thin top layer of the sample after FRP and annealed at 823K for 1h.
