Fundamentals of Metal Casting

Fundamentals of Metal Casting 98 dendritic structure As the carbon in the steel is increased however there is a greater tendency to form dendrites and hence the time to solidify increases The effect of a chill mold is to greatly decrease the time for the metal to solidify and this limit dendrite formation.
