Abstract

"The effect of copper on the solidification temperature of graphite-saturated iron-rich alloys was determined with the use of cooling curves. The ternary invariant temperature for the alloy was found to be 1172°c with the use of heating curves. At 1172°c, graphite, austenite, an iron rich liquid, and a copper-rich liquid are in equilibrium. The composition of the metallic phases was determined by weight gain, chemical analysis, and the electron microprobe. In addition, the composition of the iron-rich liquid was calculated from thermodynamic data. Isothermal sections of the iron-rich corner of the system were constructed for several temperatures in the range 1500°-1145°c. The sections are used to explain inverse segregation of copper and non-equilibrium solidification" -- Abstract p. ii
