...) for 4 h (plus 1 h for each 1 in. of casting section thickness) prior to uniform quenching in oil, the matrix microstructure will not be uniform in combined carbon. This nonuniformity reduces machinability. If the hardness is reduced by extended tempering, the resulting structure may not have a good...

.... Ductile irons are used in the as-cast or heat-treated conditions. As-cast matrix microstructures usually consist of ferrite, pearlite, or both, depending on the cast section size and/or alloy composition. Common heat treatments and their purposes and resulting microstructures include: Annealing...
