Metal Strengthening Mechanisms Materials scientists and metallurgists are often interested in designing alloys for specific applications. One property that is of prime importance is strength; the ability of a material to withstand an applied stress without failure. For metals, strength can be improved by restricting dislocation motion during plastic deformation. There are several techniques that can accomplish this, such as: 1. Solid Solution Strengthening 2. Strain Hardening 3. Precipitation Strengthening 4. Grain Size Strength
