    Fractal characterization of the fracture surface of a high-strength low-alloy steel

    The fractal dimension of fracture surfaces of a high-strength low-alloy steel (ASTM A710) has been measured using different ruler lengths. The fractal dimension increases with increasing impact toughness, E, a...

    Deformation mechanism map for creep in YBa2Cu3O7−x

    A deformation mechanism map with grain size and stress as variables was constructed for creep in YBa2Cu3O7−xat 850 and 950 °C. Theoretical models of Nabarro-Herring, Coble, and power-law creep were used for the c...
