       In this method, the average grain size of metal materials is provided。 Due to the purely geometric shapes of the metal, the metal or the alloy itself has nothing to do。 Therefore, these basic methods can be used to measure the average size of grains, crystals and cells in non metallic materials。 If the microstructure of the material is close to a standard series of rating chart, it can be used for comparison。 The average grain size is determined by comparison method, and it can also be used to measure the average grain size。 However, comparative method can not be used to measure a single grain。
