Equilibrium Phase Diagram
An equilibrium diagram shows which phases are stable in a metal at various temperatures and alloying additions. It helps in understanding microstructure formation and selecting suitable alloys.
Physical-Chemical Mechanism of Action
An equilibrium diagram visualizes the thermodynamic stability of different phases in a metal. It shows what grain or structure forms at specific temperatures and alloy contents.
Metallurgical Relevance & Risks in Welding
The equilibrium diagram is crucial for selecting the right alloy and welding process. A wrong choice can lead to undesirable microstructures, causing toughness issues or cracking.
Workshop Practice & Instructions
Use equilibrium diagrams to choose the appropriate alloy for a welding process. Pay attention to the specific temperatures and alloy additions in the diagram. Ensure the weld remains in the stable zone of the desired microstructure.
