In this paper, the influence mechanisms of nitrogen pore formation on the evolution of precipitated phase and dendritic structure during solidification process in 30Cr15Mo1N ingot have been investigated by microstructure observation, component analysis, thermodynamic calculation, and secondary dendrite arm spacing statistics. There are ferrite …
By increasing the counter ion concentration in a controlled manner, ions in solution may be precipitated individually, assuming their compound solubilities are adequately different.
The frozen forms of precipitated water include: Snow; Ice Needles; Hail; Graupel; Sleet; Classification of Precipitation. Precipitation of water vapour can be classified into different things and have different methods of formation and few of them are. 1. Raindrop.

96 Z. Yan et al. 1 3 decrease before ~ 850 °C and fall rapidly in an approximate constant slope when the temperature exceeds 850 °C. It illustrates that the γ′ phase begins to dissolve from 850 °C. When the temperature reaches the γ ′ solution temperature of Waspaloy, 1030 °C [21], or even 1050 °C, the intensity of
A precipitation reaction is a reaction that yields an insoluble product—a precipitate—when two solutions are mixed. When a colorless solution of silver nitrate is mixed …

Fischer–Tropsch synthesis (FTS) is a promising way to produce clean liquid fuels and high value-added chemicals from low-value carbon-containing resources such as coal, natural/shale gas, waste wood/plastics, and CO2 via syngas (CO + H2). Precipitated iron-based catalysts are one group of commercially viable FTS catalysts that are important in academic circles as well as in …

In solutions containing two or more ions that may form insoluble compounds with the same counter ion, an experimental strategy called selective precipitation may be used to remove individual ions from solution. By increasing the counter ion concentration in a controlled manner, ions in solution may be precipitated individually, assuming their compound solubilities are …
Here, we report on the confirmation of L1 0 FeNi phase precipitated in a multi-phase FeNiSiBPCu alloy by anomalous X-ray diffraction (AXRD). This is a powerful technique, which can differentiate between ordered and disordered phases along with the elements present in a phase. ... We measured integrated X-ray intensity with energy near the Fe ...
