... or permanent mold processes. The article lists the general guidelines of geometry in casting design. It describes the three separate contractions that are a result of cooling: liquid-liquid contraction, solid-solid contraction, and liquid-solid contraction. Factors influencing the solidification sequence...

... contractions, and tensile stresses will build up in a restrained casting that is not free to contract. Because the grain boundaries are still covered by a thin liquid layer, the material is still quite weak, and melt feeding to compensate for the solidification shrinkage is simultaneously taking place. Various...
