Polycrystalline Material - an overview | ScienceDirect …

The strength of polycrystalline materials is increased by reducing their grain size. The grain size of metals is often controlled by thermomechanical treatment, heat treatment or microalloying. Grains in aerospace alloys typically range from about 1 μm (coarse or large grains) to 1 μm (fine or small grains), and the strength increases as the grains become smaller.
