Multi Phase Field Models
In multi-phase field models, microstructure is described by set of order parameters, each of which is related to a specific phase or crystallographic orientation. This model is mostly used for solid state phase transformations where multiple grains evolve (e.g. grain growth, recrystallization or first order transformation like austenite to ferrite in ferrous alloys. Besides allowing the description of multiple grains in a microstructure, multi-phase field models especially allow for consideration of multiple thermodynamic phases occurring e.g. in technical alloy grades.

Famous quotes containing the words phase, field and/or models:
“The Indians feel that each stage is crucial and that the child should be allowed to dwell in each for the appropriate period of time so that every aspect of his being can evolve, just as a plant evolves in the proper time and sequence of the seasons. Otherwise, the child never has a chance to master himself in any one phase of his life.”
—Alan Quetone (20th century)
“Something told the wild geese
It was time to go.
Though the fields lay golden
Something whispered—”Snow.””
—Rachel Lyman Field (1894–1942)
“The parents who wish to lead a quiet life I would say: Tell your children that they are very naughty—much naughtier than most children; point to the young people of some acquaintances as models of perfection, and impress your own children with a deep sense of their own inferiority. You carry so many more guns than they do that they cannot fight you. This is called moral influence and it will enable you to bounce them as much as you please.”
—Samuel Butler (1835–1902)
