Grain Boundary Character Dependence on Nucleation of Discontinuous Precipitates in Cu-Ti Alloys
The dependence of the grain boundary character distribution for a Cu-4 at. % Ti polycrystal alloy (average grain size: 100 µm) on the nucleation of cellular discontinuous precipitates was systematically investigated. In an alloy over-aged at 723 K, cellular discontinuous precipitates consisted of a terminal Cu solid solution and a stable β-Cu₄Ti lamellae nucleated at grain boundaries. Electron ...
متن کاملOf Grain Boundary Facets
Abatraet-constraints on diffusive creep cavity growth along grain boundary facets are studied for the limiting case when all facets oriented approximately normal to an applied tensik load am uniformly cavitated. This situation represents the opposite limiting case to when cavitated facets are we&sepamted and do not intemct with each other. The analysis is done for a 3-D periodic polycrystallii ...
متن کاملFive-parameter grain boundary distribution in grain boundary engineered brass
We report the first application of a five-parameter determination of grain boundary types to grain boundary engineered alpha-brass. The most important findings were that the distribution of planes showed a prevalence of <110> tilt boundaries, especially asymmetric tilt types, and the presence of <111> twist boundaries. This distribution resulted from the low energy of these boundary types.
متن کاملGrain boundary complexions
Grain boundaries exhibit phase-like behavior in which their structure, chemistry and properties may change discontinuously at critical values of thermodynamic parameters such as temperature, pressure and chemical potential. Therefore, grain boundaries (and other interfaces such as surfaces and heterophase boundaries) can be treated as thermodynamically stable interfacial states. To differentiat...
متن کاملEffect of Grain-Boundary Phase
Two types of hot-pressed silicon nitride, one having an amorphous grain-boundary phase (6 wt% yttria, 3 wt% alumina) and the other having a predominantly crystalline grain-boundary phase (8 wt% yttria, 1 wt% alumina), were tested on a split Hopkinson pressure bar with a momentum trap, such that, in each test, the sample was subjected to a single predefined stress pulse and then recovered withou...
