phases
Phases are defined as areas in metals or alloys which have different compositions, structures, and properties. These are responsible for controlling the mechanical and physical properties of the very material. The understanding of phases is important in the way the metals behave during heat treatment and also during processing.
Key Features:
- Variation in Composition: Phases will have different chemical compositions, which will give rise to a different strength or hardness that the material has.
- Diversity of Structure: Phases may be solid, liquid, or gaseous depending on the temperature and pressure conditions.
- Mechanical Influence: The presence of several phases affects mechanical properties such as toughness or ductility.
Phases are about ensuring that there is performance and lifespan in metals and alloys. Phases are the critical factors by which metallurgy is viewed in the designing of materials to obtain properties of interest. Advances in phase techniques have bettered the understanding of and handling of metal microstructures.
