of Al and Nb elements can be easily induced in the castings of the alloys.
An EDS element line scan across areas of microsegregation
in the 0.5 Er powders (inset of Figure 2(b)) indicates cosegregation of Er and Mg as shown in Figure 2(d).
While segregation from neighborhood to neighborhood is decreasing (microsegregation
) within metropolitan areas, segregation from suburban communities (e.g., towns, villages, and cities) to other suburban communities within the same metropolitan areas and from major metropolitan cities to their suburban communities is increasing (macrosegregation).
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.
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
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.

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.
