Description

The liquidus curves of the Bi-Cu, Bi-Ag, and Bi-Au systems were re- determined by means of a sampling method. The Bi-Ag curve,was somewhat shifted from the previously determined location. The eutectic was found at 262.5 {+-} 0.2{degrees}C at 4.95 {+-} 0.05 atom % silver (2.62 wt %). The Bi-Cu liquidus agreed fairly well with Kleppa's data over the range investigated by him. The discrepancies in the literature in regard to higher copper concentrations were resolved. The.eutectic was determined to be at 270.6 {+-} 0.1{degrees} C at 0.46 atom % copper(0.14 wt % ). The Bi-Au liquidus did not agree well … continued below

The liquidus curves of the Bi-Cu, Bi-Ag, and Bi-Au systems were re- determined by means of a sampling method. The Bi-Ag curve,was somewhat shifted from the previously determined location. The eutectic was found at 262.5 {+-} 0.2{degrees}C at 4.95 {+-} 0.05 atom % silver (2.62 wt %). The Bi-Cu liquidus agreed fairly well with Kleppa's data over the range investigated by him. The discrepancies in the literature in regard to higher copper concentrations were resolved. The.eutectic was determined to be at 270.6 {+-} 0.1{degrees} C at 0.46 atom % copper(0.14 wt % ). The Bi-Au liquidus did not agree well with the few experimental data available. Below the peritectic temperature, a completely new liquidus curve was established. The peritectic.was found to be at 371 {+-} 2{degrees} C by.means.of differential thermal analysis. The composition is 23.1 atom % gold (24.1 wt %). The eutectic is at 13.4 {+-} 0.2 atom % gold (14.1 wt %) at.241.5 {+-} 0.5{degrees}C.
