Study Notes
Alloy Systems
- An alloy system is a combination of a base metal with one or more alloying elements to achieve desired properties.
Classification of Alloys
- Alloys can be classified based on the number of alloying elements:
- Binary alloys: contain two elements (base metal and one alloying element)
- Ternary alloys: contain three elements (base metal and two alloying elements)
- Multicomponent alloys: contain four or more elements (base metal and three or more alloying elements)
Phases in Alloys
- A phase in the context of alloys is a homogeneous portion of the alloy system that has uniform physical and chemical properties.
Solid Solution Formation
- In solid solution formation, the alloying element dissolves in the base metal to form a single solid phase, resulting in a mixture of atoms with a uniform crystal structure.
Eutectic Alloys
- Eutectic alloys are a type of alloy that has a specific composition and melts at a single temperature, exhibiting a unique microstructure with a combination of phases.
