Definitions
- the hardening power of copper by precipitation is optimal when the copper is kept entirely in solid solution before the precipitation treatment by quenching.
- the contribution of precipitation to hardening is all the lower the higher the precipitation temperature.
- the copper should therefore not precipitate on cooling until the tempering temperature has been reached.
- the conventional production chain does not allow the execution of such quenching necessary for maximizing the hardening power.
- the mechanical properties sought on the thin strip are essentially good resistance and good elongation under tension. This document does not, however, discuss in detail the post-casting treatments which would make it possible to obtain a sheet that can be used for industrial application.
- the object of the invention is to propose processes for the complete production of hot-rolled or cold-rolled sheets of carbon steel having high mechanical properties, in particular high strength, good anisotropy of deformations, as well as good solderability, in which a high copper content is tolerated or even desired.
- the steels obtained find a preferred application in the field of stamping, when they have been cold rolled and preferably contain at most 1, 8% of copper (the reasons will be seen later);
- Niobium and titanium may, preferably but not necessarily, be present in contents of up to 0.5% each. They produce carbides favorable to texture control, and when they are over-stoichiometric with respect to carbon, they increase the temperature Aci of the steel, therefore the solubility of copper in ferrite. Typically, each of these elements can be present at a content of approximately 0.05%. The nickel content can be up to 5%, this element being only optional. Nickel is often added in copper steels to combat hot cracking. Its action is twofold. On the one hand, by increasing the solubility of copper in austenite, nickel delays the segregation of copper at the metal-oxide interface.
