VERFAHREN ZUR HERSTELLUNG FEINKOERNIGER CU-NI-SN-LEGIERUNGEN

Cu-Ni-Sn alloys are of commercial interest in applications which involve shaping by mechanical working of an alloy as well as in casting applications. Disclosed is a method which is particularly beneficial for casting and forging applications, i.e. applications which involve only limited amounts of working or none at all. The disclosed method allows the production of a fine-grained structure in a Cu-Ni-Sn alloy by a thermal treatment which calls for maintaining the alloy at three specified distinct temperature levels for specified time periods. The resulting fine-grained alloy may undergo further processing as may be beneficial, e.g., to develop desired levels of strength and ductility.
