Grain of material
WebGrain size is important, as the traditional Hall–Petch equation (Hall, 1951; Petch, 1953) tells us: yield strength is inversely proportional to the square root of grain size. So, a very … WebGrain refinement can be achieved through the use of chemical grain refiners or other techniques such as the so-called cooling slope, spray forming, etc., all of which create a large number of nuclei that limit dendritic growth and promote the formation of the desired globular microstructure.
