Research on Heat Treatment Techniques and Structure Properties of CuNi₂TiCrZr Alloy

Abstract:

To replace the heavily contaminative and long price CuCo2Be alloy, the titanium bronze of no more than 3.5wt% alloying agents was introduced in this article, and its best techniques of heat treatment and cold deformation were confirmed. The metallurgical structures and fracture patterns were observed and analyzed respectively, and the microstructure was also surveyed by TEM. Results showed that titanium bronze belonged to deposition strengthening, and the main precipitated phase Ni3Ti distributed dispersedly in the group, whose size was about 20nm. Compared to the CuCo2Be alloy, the grain size of titanium bronze is more sensitive to temperature. So the titanium bronze can not be applied under overaging situation.
