| الوصف: | Understanding the effects of impurities, segregation, undercooling, and solidification velocity is necessary to reconstruct prehistoric As-Cu alloy manufacturing processes and practices. Moreover, these alloys often contain a wide variety of minor and trace elements such that the binary As-Cu equilibrium phase diagram does not adequately represent arsenical bronze artifacts as-cast in ancient molds. Furthermore, the variable cooling rates present in as-cast alloys of predominantly arsenic and copper, due to the thermal properties of differing mold materials, would have had profound effects on the formation of inversely segregated arsenic. Alloys with 1 to 15 wt pct arsenic were prepared and studied using differential thermal analysis, metallography, and scanning electron microscopy with energy-dispersive X-ray spectroscopy. Equilibrium diagrams were established and the potential influence of trace elements discussed. A new liquidus curve for the equilibrium diagram in this compositional range, measuring slightly higher in temperature, was established. |
