FIELD: soldering alloys. ^ SUBSTANCE: invention is intended for in manufacture of soldered parts of turbine hot tract of gas turbine engines made from monocrystalline nickel alloys. Solder is composed of following compartments, wt %: chromium 6.0-10.0, iron 0.1-0.7, boron 0.6-1.3, silicon 0.05-0.15. tungsten 2.0-5.0, molybdenum 1.8-2.2, cobalt 8.0-10.0, aluminum 4.0-6.0. carbon 0.05-0.2, niobium 3.0-5.0, and nickel - the balance. ^ EFFECT: limited erosion activity, improved heat resistance of soldered connections, and improved workability in soldering operation due to spreading ability. ^ 2 tbl, 3 ex |
