ПАЯНЫЯ - ПЕРСПЕКТИВНЫЙ МЕТОД ОТРИМАННЯ НЕРОЗ'СМНИХ З'СДНАНЬ

The paper presents practical results of developments and investigations in the field of brazing various materials: aluminium, copper, high-temperature nickel and titanium alloys, as well as promising materials based on Ni3Al and TiAl intermetallics, and steels of different grades. Data on reactive-flux brazing of aluminium thin-walled structures in a controlled gas environment are given. A lot of attention is paid to producing brazed joints from dissimilar materials: Mo+C (stainless steel), W+Cu, hard alloy material (VK 20)+steel, Al+steel, etc. Effective application of the developed technologies of brazmg high-temperature nickel and titanium alloys in fabrication of critical structures for high temperature applications and results of mechanical testing of brazed joints are shown. The developed brazing filler metal and technologies of high-temperature vacuum brazmg were applied to produce joints from new generation alloys based on nickel and titanium aluminides, which have been successfully tested for long-term strength under the conditions of higher temperature and continuously applied stresses.
