The peritectic reaction
WebbPeritectic reaction in iron-carbon phase diagram takes place at constant temperature of 1493 o C. 9. Which of the following reaction does not exhibit mushy zone in Fe-C phase diagram? WebbA peritectic reaction is a reaction where a solid phase and liquid phase will together form a second solid phase at a particular temperature and composition - e.g. Liquid + alpha --> beta These reactions are rather sluggish as the product phase will form at the boundary between the two reacting phases thus
