Abstract

"Gas carburization experiments were conducted at 950ºC 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 950º, 1000º, and 1050ºC. The results of gas carburization and graphite solubility experiments at 950ºC 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 1000º and 1050ºC 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, page ii.
