摘要According to the requirements for the beam collimation system of the rapid cycling synchrotron (RCS) of China Spallation Neutron Source (CSNS), the main structure of a scraper of primary collimator is made by W/Cu brazing, in which the thickness of tungsten slice is 0.17 mm. In order to get the best mechanical properties, the brazing temperature is suggested to be controlled under the recrystallization temperature of tungsten, while the recrystallization temperature is affected directly by the thickness of tungsten. Because of little research and application on the brazing of thin tungsten slice of 0.17 mm and copper, tensile tests are done to get the mechanical properties of tungsten slices which experience different brazing temperatures. In keeping the inner relationships between the mechanical properties and temperature, another experiment is done by using SEM to scan the microstructures including the size and distribution of crystals. Finally we determine the recrystallization temperature of tungsten slice of 0.17 mm, and get the best parameters of W/Cu brazing for scrapers of primary collimator in CSNS/RCS.
