Ultra-strength materials (2010, background): “The ultra-strength phenomenon in nanocrystalline materials involves an interesting possibility of the strongest grain size [296,297].”
Mechanics of Solids and Materials (2006, background): “Recently, Asaro, Krysl, and Kad (2003) developed a simple yet compelling mechanistic model for the likely scenario for the anticipated transitions in deformation mechanisms that appears to be quite consistent with experimental observations that exist to date and that leads to a complete…”
Nano-sized twins induce high rate sensitivity of flow stress in pure copper (2005, unknown): “Such analyses imply phenomenological responses for strain rate sensitivity that are different for different fcc metals and also point to elevated flow stress values [42,47].”
Mechanistic models for the activation volume and rate sensitivity in metals with nanocrystalline grains and nano-scale twins (2005, methodology): “Our analysis begins with consideration of a partial, or perfect, dislocation emitted from a grain boundary, as envisioned in [42] and schematically sketched in Fig.”
Atomistic based continuum investigation of plastic deformation in nanocrystalline copper (2006, methodology): “First, there is evidence (Asaro et al., 2003; Chen et al., 2003; Liao et al., 2004) that partial dislocation emission in copper is energetically favored compared to full dislocation emission at these small grain sizes.”
