Alternative Title

Age of hardening of copper manganese nickel alloys

Abstract

"The Bureau of Mines in conjunction with their Electrolytic Manganese Alloys program has developed a series of age hardening copper-manganese-nickel alloys having properties which compare favorably with those of copper-beryllium alloys...An unusual and highly desirable characteristic of these alloys is their insensitiveness to rate of cooling from the solution temperature. Air cooled and water quenched samples will have identical time hardness curves on being aged. Instead of requiring closely controlled conditions characteristic of many age hardening alloys, these alloys cannot be subjected to a thermal mechanical handling which will prevent hardening on their being subsequently heated to the aging temperature. The reaction of these alloys to heat treatment is of such an unusual nature that the following investigation was undertaken to attempt to clarify the hardening mechanism of these alloys"--Introduction, page 1-2.
