| 内容記述 | It has previously been noted that, for a given alloy system, microstructural manipulation may result in large variations in hydrogen susceptibility at a given strength level; it may even be possible to obtain inversions of susceptibility in which higher strengths may be associated with greater embrittlement resistance. An examination is presently conducted of the consequences of hydrogen-heterogeneity interactions, or 'trapping', in several alloy systems; these will include both conventional ferrous and nonferrous ones, and novel alloy systems. Deleterious trapping dominates behavior in the presence of large local concentrations of hydrogen; plasticity modifications due to hydrogen exercise a dominant influence on embrittlement susceptibility when relatively weak traps are present, as well as when a more uniform distribution of hydrogen is present. |
