Abstract
Based on the results of systematic studies of Ti-Zr-Co system alloys and allowing for published data, the liquidus surface of this system was plotted by using the simplex-lattice experimental design method. This system was found to have a region of alloys with decreased liquidus temperature, the most promising in terms of filler metal development. Spreading of experimental filler metals over titanium alloys of different classes (OT4, VT6 and VT22) was studied. The data on mechanical properties of the brazed joints are given.
