Concept
Alloying is the process of combining two or more elements, at least one of which is a metal, to create a material with enhanced properties such as increased strength, corrosion resistance, or ductility. This process is fundamental in materials science and engineering, enabling the development of metals with tailored characteristics for specific applications.
Relevant Fields:
A solid solution is a homogeneous crystalline structure where two or more elements are completely soluble in each other in the solid state, forming a single-phase system. This occurs when the atomic sizes, crystal structures, and electronegativities of the elements are compatible, allowing one element to substitute for another within the lattice without disrupting the overall structure.
