Paton Electric Welding Institute of the National Academy of Sciences of Ukraine popup.description2 Object - alloys of Pd-Ni-Me (Si, Ge, Co, B) system, vacuum brazing of heat resistant nickel alloys (VB NBA). Aim - to develop high-strength brazing filler metal, technology of its manufacture, technology of high-temperature VB HNA and dissimilar joints. Methods - study of melting interval and phase transformation (VDTA-8); optical and electron microscopy; micro X-ray spectrum analysis; standart procedure for tensile tests at room and elevated temperature with application of simple stresses. Obtained - data on structure, intervals of melting. capillary properties of multi-component Ni-Pd alloys. Determined was an effect of alloying elements on structure peculiarities of Pd-Ni-Me brazing filler metals and their capability of plastic deformation. Developed - high-temperature Pd-Ni-Cr-Ge brazing filler metal and scientific basics of high-temperature VB HNA. Experimental-industrial check of the brazing filler metal (mechanical tests at room temperature T and elevated (550 C, 785 MPa) showed long term strength which is tow times higher than that of commercial brazing filler metal. Developed scientific basics will be used in development of technology for specific products in aircraft, shipbuilding, oil transport industries. Product Description popup.authors Воронов В. В.
