Alloytropes are distinct structural forms of an alloy that exhibit different physical properties and characteristics, similar to allotropes in pure elements. These variations can arise from differences in composition, temperature, or processing conditions, leading to alterations in microstructure. Examples include the different phases of steel, which can exist as ferrite, austenite, or martensite, each with unique mechanical properties. Understanding alloytropes is crucial for tailoring materials for specific applications in engineering and manufacturing.
