Which type of metal typically exhibits greater resistance to deformation?

Hard metals are known for their increased resistance to deformation due to their high hardness and strength. This characteristic arises from their internal structure, which often includes tightly packed atoms that create strong bonds, making it more difficult for dislocations (defects in the crystal structure) to move. When stress is applied to hard metals, they tend to maintain their shape and integrity better than softer materials.

In contrast, ductile metals can undergo significant deformation before failure, meaning they are more malleable but less resistant to initial deformation. Soft metals, while easy to shape and work with, have lower strength and are more prone to deformation under stress. Composite metals can provide a mix of properties, but their performance will vary based on their composition.

As such, hard metals are traditionally the best suited for applications that require materials to withstand significant forces without changing shape.
