Alloying

Definition

Alloying is the process of combining two or more metals, or a metal and another element, to create a material with enhanced properties compared to the individual components. This technique is crucial in metallurgy as it allows for the development of materials that exhibit improved strength, corrosion resistance, and malleability, which are essential for various applications throughout history.

5 Must Know Facts For Your Next Test
