Layering

Definition

Layering refers to the process of combining different types of materials or metals to create a composite material with distinct physical properties. This technique is especially significant in metallurgy, where it enhances the strength, flexibility, and aesthetic qualities of tools and weapons. In historical contexts, layering was often achieved through methods such as pattern welding and crucible steel production, which resulted in materials that had both functional and artistic value.
