These sources explain how alloys are created by mixing primary metals with other elements to improve their structural properties. While pure metals are often soft because their atoms can easily slide past one another, the introduction of different-sized atoms disrupts the internal lattice, making the material significantly harder and stronger.
Common examples include bronze, brass, and steel, which are engineered for specific uses such as construction, maritime hardware, and musical instruments. Beyond physical strength, alloying can enhance a material’s resistance to corrosion and alter its aesthetic appearance, as seen in various grades of gold and stainless steel. Ultimately, these materials are homogeneous mixtures designed to overcome the natural limitations of pure metallic elements.

To be able to use metals effectively in engineering, it's important to have an understanding of how they are structured at the atomic level.
In this video we'll explore metals, their microstructure, and various techniques like grain boundary strengthening, solid solution strengthening, precipitation hardening and work hardening that can be used to improve their properties.
We'll also cover phase diagrams, focusing on the diagram for Iron-Carbon atoms, that shows us the different phases like ferrite, austenite and cementite that can be found in steels for equilibrium conditions.
