摘要：

The effect of stacking fault energy (SFE) on the tensile stress-strain behavior of nanocrystalline face-centered cubic (fcc) metals was investigated. The stacking fault energy of nickel was decreased by alloying with copper or iron. It was found that, as predicted by a recent simulation study, decreasing the SFE increases the strain hardening rate of the nanocrystalline fcc metals. The effect was more pronounced in the nickel-copper alloy, which had a smaller average grain size. (C) 2004 American Institute of Physics.
