... if the material property values are to be useful. For example, consider a situation in which a material supplier produces new heats (batches or lots) of material and wishes to monitor the “quality” of the product, which in this case will be described simply by the ultimate tensile strength.

A dirty melt having lots of oxides and inclusions may also have extra nucleation sites to initiate solidification. When that happens, the earlier solidification and growth will lower the fluidity of the molten...
