Study Notes
Definition of Alloys
- An alloy consists of a metallic base, typically comprising the majority of the material, combined with metal or non-metal components as property modifiers.
- Alloys are engineered through experimentation to exhibit specific desirable properties not present in the base material.
Composition of Alloys
- Alloys are formed by merging a primary base element with various secondary elements.
- The base element serves as the foundational structure and solubility medium, uniformly dispersing secondary elements.
- Secondary elements are added in precise proportions to enhance the final material's properties.
- The final alloy showcases a mixture of characteristics from all constituents, often resulting in unexpected performance improvements that individual components do not exhibit.
Alloy Production Process
- Alloys are created through smelting and blending the base metal with additional elements, followed by cooling.
- The mixing can occur while in a molten state; however, non-metallic additives may be incorporated post-solidification using various methods.
Types of Alloys
- Two main families of alloys exist: substitutional and interstitial.
- Substitutional Alloys (e.g., brass, bronze) are formed when atoms of the alloying elements, which are similar in size to the base metal atoms, occupy the same lattice sites.
- This substitution allows for property adjustments within the material's lattice structure, enhancing its overall strength and stability.
- Substitution often stresses the lattice, reducing planar slip potential by creating barriers that obstruct movement.
