Definitions
- Copper alloys having a small zirconium content of the order of 0.1 to 5.0% have been heated to temperatures in the range of from 700 to 1000 C., at which temperature the alloy is solution annealed, the heated alloy then being quenched.
- copper-zirconium alloys having a zirconium content of the order of 0.01 to 0.15% be quenched after solution annealing, followed by cold working to reduce the cross sectional area thereof.
- Such alloys are suitable as conducting elements such as commutator segments in electric motors where optimum mechanical strength of the material perpendicular to the direction of forming the material is important.
- semi-finished materials such as rods, wires, etc., such a procedure is without advantage, since the ordinate of the perpendicular direction cannot be clearly defined.
- an object of this invention is to provide an improved procedure for making semi-finished materials from hardenable copper alloys wherein the cast alloy in its heated condition is brounght to its solution annealing temperature and at such temperature the alloy is Worked to reduce the cross sectional area thereof to a desired form and immediately thereafter is quenched.
- Another object of this invention is to provide a procedure of the character described wherein the heating of the alloy to effect solution of the alloying constituents is also used in the working of forming operation, to thereby reduce manufacturing costs and to improve the quality of the product as by producing a fine grain structure, rather then the coarse grain structure produced when hot pre-formed material is separately solution-annealed.
- a further object of this invention is to provide a procedure of the character described wherein the immediate quenching of the hot material after it has been worked in the hot state, is effective to eliminate oxygen absorption along the surface of the metal. Such oxygen absorption leads to embrittlement of the skin surface when exposed to hydrogen at elevated temperatures, as in a brazing operation, unless the outer layer is later removed in a separate machining operation.
- Still another object of this invention is to provide a procedure of the character described whereinafter the quenching step, to further treat the alloy product in successive heat hardening, cold-forming and additional heat hardening steps.
- the quenching step to further treat the alloy product in successive heat hardening, cold-forming and additional heat hardening steps.
- the process of the instant invention is useful for making roller electrodes used for electric resistance welding.
- An alloy for such purpose consists of 0.6% chromium with the balance copper.
- the rollers are made from cast billets or compressed rod material and are hot compressed when the material has been heated to its solution-annealing temperature. The resultant discs are quenched immediately after hot compression.
- the rollers show a constant fine grain structure across the entire cross-section of the material with grain sizes of 25-60 microns.
- the article also exhibits a substantial increase in hardness.
- Typical heat hardenable copper alloys which may be used with the process of the instant invention, include:
- a copper-chromium-zirconium alloy having a content of 0.6% chromium; 0.1% zirconium, with the balance copper.
- the solution annealing temperature is above 950 C.
- a method of converting a heat hardenable copper alloy to a semi-finished form comprising heating said alloy in its cast state to its solution-annealing temperature, immediately working the heated alloy to a predetermined semi-finished form of reduced cross sectional area, and immediately thereafter quenching the same.
