Re-solution of Precipitated Silver in Copper-Silver Alloys
During preliminary tests on the aging of a Cu-plus 5 pct Ag alloy, a specimen which had been overaged 24 hr at 550°C was annealed in a nitrogen-hydrogen atmosphere first for 2 hr and then for an additional 28 hr at 600° C. Conceivably, for Cu-Ag alloys, the matrix-transition-precipitate precipitation sequence is reversible for the … Read more
