  • Creep at very low rates
    Thumbnail
    Author: Nabarro, FRN Date: Feb 2002 The creep rate in a land-based power station must be less than 10(-11) s(-1). At these low rates of deformation the transport of matter occurs by the migration of vacancies rather than by the glide of dislocations. A quantitative understanding ... Read more
  • Stress-driven grain growth
