Satellites

Definition

In the context of metallurgy, satellites refer to smaller pieces of metal that form around larger metal objects during the smelting process. These smaller formations often occur when molten metal cools unevenly, leading to variations in composition and structure, which can affect the properties and applications of the final product. Understanding how satellites are formed and their implications on metallurgy is crucial for advancements in material science and technological progress.
