摘要: Abstract The effect of temperature on the cyclic stress-strain response, high cycle fatigue life and near-surface interior dislocation structure was determined for copper polycrystals in range 295-83 K. A reduction leads to a shift curves stress-number cycles failure (S-N) higher stress values, while Coffin-Manson plot is independent. These results are discussed basis corresponding changes characteristic spacings structure.
