Sphere ≥0.399 (dependent on grain size) Cube 0.425 Cylinder 0.429 Disk 0.453 2.2.4 Grain Size Distribution Real rocks contain a distribution of grain sizes, and often the grain size distribution is multi-modal. The best way of understanding the effect is to consider the variable admixture of grains of two sizes (Figure 2.4).

Superalloys can have 3 types of grain patterns: equiaxed polycrystalline, columnar polycrystalline, and single crystal. Equiaxed grains are the "default" pattern for metals. Each grain is roughly the same size and shape. Most methods of solidifying from liquid will result in an equiaxed polycrystal.Lithographic limestone is a dense rock with a very fine and very uniform grain size. It occurs in thin beds which separate easily to form a very smooth surface. In the late 1700s, a printing process known as lithography (named after the stones used) was developed to reproduce images by drawing them on the stone with an oil-based ink, then using ...
