The Effect of Zirconium Content on Heat Treatment Process and Properties of High Purity Copper Forgings

The change of heat treatment process and properties of the alloy is introduced in this paper when 0.1%~0.3%(w)zirconium is added to high purity copper.The test result indicates that zirconium has a little effect on the best solution temperature of high purity copper forgings,but the best aging temperature of alloy rises with the increase of the amount of zirconium.The stability of smelting yielding rate of element zirconium is poor in the industrial production.So batch heat treatment is not fit for high purity copper forgings with element zirconium,and the actual content level of zirconium should be the base of mapping out heating process.
