The peritectic reaction
WebbFurthermore, two peritectic reactions were observed and the course of liquidus lines was determined in the whole investigated composition range. The new phase diagram differs considerably from all previous versions, and, for the first time, gives a complete rationalization of the crystal structures observed in the debated composition area. Webb4 dec. 2011 · Peritectic reaction is a reaction in which two phases (solid and a primary solid phase alpha) in converted into a single phase beta. Differs from eutectic reaction. Unlike eutectic...
