Coherent precipitation of copper in Super304H austenite steel
Materials Science and Engineering: A, 2013Abstract The precipitation behavior of copper-rich phase in an austenitic stainless steel and the interface structure between the precipitates and the matrix have been investigated combining transmission electron microscopy and coarsening analysis. The fine dispersed Cu precipitates were spherical and highly stable in the austenite matrix, with the ...

Coherence Among Climate Signals, Precipitation, and Groundwater
Groundwater, 2010Climate signals may affect groundwater level at different time scales in different geographical regions, and those patterns or time scales can be estimated using coherence analysis. This study shows that the synthesis effort required to search for patterns at the physical geography scale is possible, and this approach should be ...

HREM of coherent precipitates in ZrO2 alloys
Ultramicroscopy, 1987Abstract Coherent precipitates in ZrO 2 alloys, particularly those containing MgO or Y 2 O 3 , are the dominant microstructural feature in strong and tough transformation-toughened ZrO 2 -based ceramics. HREM has been used to study such precipitates in Mg-PSZ and Y-PSZ (MgO and Y 2 O 3 partially stabilized ZrO 2 ).

Coherent equilibrium in alloys containing spherical precipitates
Acta Metallurgica et Materialia, 1995Abstract Coherent equilibrium is investigated theoretically in alloys containing monodispersed spherical precipitates. The alloy system is subjected to a Dirichlet tessellation by constructing a Voronoi polyhedron around each particle, and for the purpose of calculation each polyhedron is approximated as a sphere. The basic unit of the microstructure

Anterior segment optical coherence tomographic characterisation of keratic precipitates
Contact Lens and Anterior Eye, 2020Anterior segment optical coherence tomography (AS-OCT) can be used to visualise keratic precipitates (KPs) on the corneal endothelium. However, there has been no correlation between characteristic clinical appearances of KPs and AS-OCT morphology. We wished to assess the potential diagnostic role of AS-OCT in patients presenting with inflammatory eye ...

Coherent Precipitation near Dislocations. A Theoretical Analysis
Physica Status Solidi (a), 1979A simple theoretical model is developed for a dislocation decorated by a cylindrical precipitate, which makes it possible to derive the energy change ΔW associated with the precipitation process versus radius R of the precipitate. The distance a between the cylinder axis and the dislocation line is taken so as to minimize ΔW.
