polycrystalline

adj. comprised of two or more crystals; comprised of many crystals with different orientations

A polycrystal is a material that is made of many smaller crystallites with varying orientation. The variation in direction can be random (called random texture) or directed, possibly due to growth and processing conditions. Fiber texture is an example of the latter.Cf. monocrystal.Almost all common metals, and many ceramics are polycrystalline. The crystallites are often referred to as grains.
