P91 steel is an important bearing material used in nuclear power plants. The study of its mechanical degradation behavior is important for ensuring safe operation. The relationship between the dislocation density of P91 steel under different strains and the corresponding nonlinear ultrasonic parameter β...
6a, the initial current of samples is around 50 mA cm−2 and 110 mA cm−2 in 1 M KOH electrolyte, respectively. After 20 h test, the current density of Cr–FeNi LDH @ ESS sample revealed negligible change at potential of 1.56 V vs. RHE, and slight reduction at 1.65 V vs. RHE...
(For the developing microstructure in case iron nitride can develop, see Section 7.3 under ‘weak’ interaction.) Upon nitriding of a specimen of Fe-4.65at% Al a high density of microcracks appears along the original grain boundaries in the ferrite matrix. These microcracks arise by recombination...
The so-called acceleration response β, along the mega-sub structural floor number to various severe earthquake waves, was utilized to further characterize the damage probability matrix, which can be conveniently expressed in terms of a probability density function [38]. 3. Results and Discussions ...
