The Influence of Other Alloying Elements

Introduction Equilibrium phase diagrams are a convenient and concise way of representing the most stable relationships between phases in alloy systems. 

Phases A phase is some portion of a body of material throughout which the physical and chemical characteristics are homogeneous. 

Microstructure Three microstructural characteristics that are important for multiphase alloys are The number of phases present The relative proportions of the phases The manner in which the phases are arranged Three factors affect the microstructure of an alloy  

Equilibrium Diagrams Having Intermediate Phases or Compounds 

What phase(s) is (are) present—from the location of the temperature-composition point on the phase diagram.
