Precipitation hardened alloy on the basis of copper, zinc, nickel and manganese exhibiting a high strength and ductility with values similar to those of stainless steels in combination with excellent machinability. The inventive alloy family is characterized by fine fibre-like or globular precipitates that emerge during intermediate temperature annealing treatments, which in case of the unleaded variations significantly improves the machinability. The alloy of invention is particularly suited for free machining applications such as the production of pen tips and reservoirs for writing implements of reduced tip dimensions, where conventional Cu—Ni—Zn—Mn alloys fail due to lack of strength and where the corrosion resistance in gel-based inks is insufficient without restriction to other fields of application.

The balance of the alloy is cobalt and usual impurities. The wire is annealed at a combination of temperature and time effective to provide a grain size of about ASTM 6 or finer. The annealed wire is then drawn such that the cross-sectional area of the wire is reduced by about 50 to 80%. The as-drawn wire is then heat treated at a second combination of temperature and time effective to provide the wire with high strength and sufficient ductility that when the wire is wrapped to provide a coil having an inside diameter substantially commensurate with the diameter of the wire and then unwrapped it does not crack or break.

PCT No. PCT/US92/11261 Sec. 371 Date Mar. 7, 1997 Sec. 102(e) Date Mar. 7, 1997 PCT Filed Dec. 18, 1992 PCT Pub. No. WO94/14993 PCT Pub. Date Jul. 7, 1994Austenitic steel intended for use in radiation areas of nuclear reactors is largely resistant to irradiation-induced stress corrosion cracking if its silicon, phosphorus and sulfur contents are reduced in relation to standard commercial steel quantities and its grain structure has finely dispersed carbide precipitation, particularly of niobium carbide. The finely dispersed distribution can be induced in that larger niobium precipitation takes place at annealing temperatures between 1100 and 1150 DEG C., and carbide is precipitated through the corresponding annealing at temperatures of approximately 750 DEG C.
