• Mechanistic models for the activation volume and rate sensitivity in metals with nanocrystalline grains and nano-scale twins (2005, background): “The strain-rate sensitivity index, defined below, is an order of magnitude higher for metals with nanocrystalline structures [5–11].”
• Nano-sized twins induce high rate sensitivity of flow stress in pure copper (2005, unknown): “…indentation experiments performed at loading rates spanning three orders of magnitude on specimens with the higher density of twins (twin lamellae width 20 nm) revealed an up to sevenfold increase in rate-sensitivity of hardness compared to an essentially twin-free pure Cu of the same grain size.”
• What is behind the inverse Hall–Petch effect in nanocrystalline materials? (2007, result): “The model’s second prediction is that the CYS depends significantly on strain rate, which confirms previous research [52–57].”
