| Summary |
"Gas carburization experiments were conducted at 950°C in order to study the phase relations and to determine the activity of carbon in the iron-rich corner of the iron-copper-carbon system. The solubility of graphite in equilibrium with iron-copper alloys was determined at 950°, 1000°, and 1050°C. The results of gas carburization and graphite solubility experiments at 950°C were used in constructing an isothermal section of the iron-rich end of the iron-copper-carbon phase diagram, on which are superimposed carbon isoactivity lines. Graphite solubility data at 1000° and 1050°C were used to construct similar diagrams without the isoactivity lines. The effect of carbon content on the solidus temperature of an alloy initially containing 90% copper and 10% iron was studied by gas carburization and graphite equilibration techniques. The effect of copper on the rate of carburization was determined in a semi-quantitative way. The results are discussed in terms of application to heat treatment of copper bearing steels and to the liquid phase sintering of iron-copper-carbon powder metallurgy parts"--Abstract, leaf ii. |
