Research on heat treatment techniques and structure properties of CuNi2TiCrZr Alloy
Copper alloy is the first choice to be engineering materials of electric and thermal conductivity1. With development of the industrial accoutrement technique, engineering parts present higher requirements on the combination property that copper alloy is expected to be of high strength and heat-durability as well as of electric conductivity2, 3, 4. The typical material of high strength, heat-durability and electric conductivity is the CuCo2Be alloy, which has been used widely in engineering. However, the scarcity and long price of alloying agents Co and Be make the cost of CuCo2Be alloy always very high. And the dust of Be and its compounds generated during the fusion cast of CuCo2Be alloy are one of the most poisonous industrial pollutant. The production of copper alloy including Be does severe harm to workers health and the environment5. All the reasons above make both material workers and related industry to apply themselves to research and develop substitution for copper alloy including Be. At present, the reported and industry standard formed substitution for Be-bronze is the CuNi2SiCr alloy6, which is of higher strength but lower electric conductivity reduced by 15％ than CuCo2Be alloy, so whose application is limited at a certain extent. The combination property of the CuNi2TiCrZr alloy studied in this article reaches the level of CuCo2Be alloy, but its technique condition requirements are very rigorous and its quality control in industrial production is very difficult. So there is great significance to do research on the processing techniques and properties of CuNi2TiCrZr alloy.
