TI  - Surface nanocrystallization of pure Cu induced by ultrasonic shot peening.
PG  - 9637-43
AB  - Peening is mainly used as a method of surface treatment for microstructural 
      modification in order to improve surface mechanical properties. The ultrasonic 
      shot peening (USP) technique can cause severe plastic deformation with its high 
      strain rate on the surface of metallic parts. However, systematic studies of 
      microstructural refinement mechanism upon plastic deformation with consideration 
      of alloy systems are rare. In this study, USP-treated Cu samples of 99.96% purity 
      was examined using analytical techniques, Vickers microhardness test, electron 
      backscattered diffraction (EBSD) and transmission electron microscopy (TEM). 
      Results of EBSD and microhardness analyses indicated grain refinement with 
      deformation structures and hardness increase down to 400 mum in depth upon 
      treatment. Depth specific TEM analysis of the samples revealed the steps of the 
      grain refinement process to the formation of randomly oriented fine grains.
