In all cases the mould had previously been heated in a concentric gas-jet crucible furnace up to a certain temperature before the molten metal was cast in it. The temperature was measured with a thermocouple which was inserted into a hole (a) in the mould. The ingot, after this treating, was slowly cooled in the furnace or quenched in water. It was then examined microscopically and chemically. The arrangement adopted is sketched in Fig. 1. The average temperature throughout the experiment is cited as the "temperature of the mold" for the sake of convenience, where necessary. The first table shows the conditions of the experiments. The carbon was determined by the wet combustion method (chromic acid method). Graphite in the ingots, if present/was very liable to be lost in the preparation of the samples for analyses, so that all due care was taken, in sampling, to avoid this. In those cases where graphite appeared in certain confined portions distributed in the ingots, the analysis etc. Indeed, the graphitization in the experiments is almost entirely due to the slow cooling of the metal at or near its solidification point. Graphite is always to be seen in an ingot which was slowly cooled, even when there is practically no silicon, which was formerly supposed to be necessary in graphitization. No. 5 and No. 6 underwent nearly the same heat treatments, and differed only in carbon contents. The percentages of carbon in these two alloys were found to be 3.93 per cent and 3.45 per cent respectively. The microscopical structures of the two did not differ greatly. No. 5 contained more graphite (2.18 per cent) than No. 6 (1.53 per cent). So far as the present results a...
