Nano-sized twins induce high rate sensitivity of flow stress in pure copper

  title={Nano-sized twins induce high rate sensitivity of flow stress in pure copper},
  author={Lei Lu and R. Schwaiger and Z. W. Shan and Manh-Tuan Dao and Kung.-Yu Lu and Swaathiratna Suresh},
We have investigated the rate sensitivity of flow stress and the extent of strengthening in polycrystalline copper containing different volume fractions of nano-sized twins, but having the same average grain size. The specimens were produced by pulsed electrodeposition, wherein the concentration of twins was varied systematically by varying the processing parameters. Depth-sensing instrumented indentation experiments performed at loading rates spanning three orders of magnitude on specimens… CONTINUE READING
