In casting, cellular solidification is highly advantageous from the standpoint of reducing or eliminating the defects associated with dendritic solidification, including microporosity,
microsegregation, and hot-tearing.
Characterization of peritectic reaction in medium- alloy steel through
microsegregation and heat-of-transformation studies.
A study of microstructure and
microsegregation of aluminium 7050 alloy.
Although the electrode must be sound and stress relieved to prevent cracking or fragmentation during melting, the presence of minor central cavities and substantial
microsegregation are permitted.
They cover component casting, cast house processes, casting hydrodynamics, heat transport during component casting and cast house processes, structure and structure formation in cast materials,
microsegregation in alloys, heat treatment and plastic forming, precipitation of pores and slag inclusions during the casting process, solidification and cooling shrinkage of metals and alloys, and macrosegregation in alloys.
Boettinger, Prediction of dendritic growth and
microsegregation patterns in a binary alloy using the phase-field method, Acta Metall.
A possible explanation is that the viscoelastic behavior for these compositions and the temperature range of interest here is dominated by the AA component, as a result of
microsegregation of AA due to formation of H- bonds between COOH- groups of AA and ester groups of flexible CPU- blocks.

Microsegregation in Alloys - Peritectic Reactions and Transformations.
The two types of segregation are
microsegregation and macrosegregation.
Martensite structure between carbide lines is of non-acicular nature because of
microsegregation, and in the areas of accumulation of carbides acicular martensite with low etching capacity is present.
There are four main areas detailed: fundamentals of solidification synthesis, which examines issues related to stir mixing, pressure infiltration, transfer of particles or fibers through gas-liquid and liquid-solid interfaces, and particle/fiber interactions with fluids; processing and microstructures, which focuses on microstructure formation during solidification of MMC under different conditions, such as nucleation, growth, heat transfer,
microsegregation, macrosegregation and interactions between solidifying interfaces, particles and fibers; and, properties of solidification processing, covering the relationship between the microstructures and properties.
In a paper describing their work, Sarum Boonmee, Molly Moran and Doru Stefanescu explained the endurance limit that arises in the presence of casting skin, developed a "fatigue skin factor" to quantify the effect the skin has and evaluated the
microsegregation of the alloy surface.
