| Summary |
"It is known that the number of temper carbon nodules per unit volume of malleable iron has an effect on both the rate of anneal and on the resulting physical properties, but neither have been clearly worked out quantitatively. The purpose of this investigation is to ascertain the effect of temper carbon nodule number on certain of the physical properties of a commercial malleable iron. Quantitative determinations of the effect of temper carbon nodule number would be essential from a theoretical viewpoint in working out the mechanism of graphtization, and would be useful in commercial practice in showing the most desirable nodule count and matrix structure to have in order to produce optimum mechanical and physical properties. The metallurgical potentialities of malleable iron will not be fully realized until the graphite formation during the annealing cycle and the resulting physical properties due to this formation are fully understood and controlled"--Introduction, leaf 1. |
