... hydrogen embrittlement mechanism has been stress-induced niobium hydride formation in E-Brite; whereas, this mechanism has been hydrogen trapping and absorption by nitrogen and faceted titanium carbo-nitrides in the vicinity of grain boundaries in 26-1S. Stress corrosion crack propagation of these alloys...

... performed with the objective to (1) determine the solubility limits of iron and chromium in a Zr 1.4% Sn matrix, (2) characterize the precipitates formed when the maximum solubility is exceeded, and (3) study the growth mechanism of precipitates in alloys with different (iron + chromium) content. Zirconium...

... progressively. The variation of fatigue life was ascribed to the occurrence of some considerable interactions between creep, high-cycle fatigue (HCF), LCF, and environmental effect under different values of Q at elevated temperature, and the change of damage mechanism of the material. The total LCF life...

... The effects of alloy chemistry and thermal processing on corrosion performance of Zircaloy are shown to provide significant insights into the mechanisms governing nodular corrosion formation. Nucleation and growth behavior of nodular oxide in ex-reactor and in-reactor tests were studied...

... pathway of how lubricants degrade. The acid number increase was found to be an important parameter in monitoring the lubricant degradation mechanisms. catalysis degradation environmental effects lubricant mechanism oxidation viscosity increase wear Stephen M. Hsu} Charles S. Ku...

... recent findings of test programs are discussed and a detailed mechanism proposed for the dispersion process. It is proposed that a mathematical model be sought to express effectiveness as a function of the volumes of oil, water, and dispersant, oil viscosity, water salinity, and application method...

... by their removal of hydrogen from the surface of iron causing it to go into solution. Evidence is presented which indicates that this mechanism may not be responsible for the main corrosive effect of these organisms. These bacteria appear to cause corrosion by producing extracellularly, under anaerobic conditions...

... spectrophotometry. Methods of eliminating interferences in atomic absorption determinations are discussed. Mathematicial correction can be applied in lieu of slag analysis which cuts down the analysis time by 50 percent. A mechanism for slag formation is proposed. blended metal powders arc melting...

... An overview of the mechanism of chemical dispersion is presented in order to put the subject in the proper perspective. The methodology and role of the surface active agent in the generation of finely dispersed oil droplets are reviewed. This discussion of the dispersing mechanism will help...
