The solubility of C in solid Cu

The solubility of C in solid Cu was determined in the temperature range 1143-1293 K. Layers of C were vapour deposited onto high-purity Cu slices, which were annealed for 72 and 240 h at different temperatures. The C content in the samples was determined by means of combustion analysis. A Henrian behaviour for the carbon activity in the interstitial solid solution was observed. (C) 2004 Acta Materialia Inc.
