20^th Alemi Meeting

Alloying Element Effects on Migrating Interfaces

ALEMI is a response to two scientific/technological driving forces: the first is an increasing emphasis on the modeling of the phase transformations in steels with the object of predicting the microstructural consequences of their processing; the second is a related renewed interest in the fundamentals of alloying element interactions with transformation interfaces. A series of annual informal workshops was initiated with focus on the effects of alloying elements on the growth of ferrite from austenite.

Key literature
