Abstract

The invention discloses a nickel-based interlayer alloy material, a preparation method of the nickel-based interlayer alloy material, a weldment, a welding method and application, and relates to the technical field of welding materials. The nickel-based interlayer alloy material comprises the following chemical components in percentage by weight: 11.9-13.2 percent of Cr, 6.5-7.8 percent of Co, 0.5-1.7 percent of Mo, 4.1-5.2 percent of W, 2.4-3.6 percent of Al, 4.1-5.3 percent of Ti, 3.0-4.2 percent of Ta, 0-3.1 percent of Re, 1.5-3.1 percent of Ru, 0.5-1.1 percent of B, 0.3-0.8 percent of Si and the balance of nickel. The preparation method comprises the step of smelting the metal and / or the alloy into the nickel-based intermediate layer alloy materials according to the chemical composition. The welding method comprises the step of welding the weldment by adopting the alloy materials. The weldment is obtained by welding through the welding method. A weldment joint obtained by welding the alloy materials is high in high-temperature strength.

Description

technical field [0001] The invention relates to the technical field of welding materials, in particular, to a nickel-based interlayer alloy material, a preparation method thereof, a weldment, a welding method and an application thereof. Background technique [0002] With the continuous improvement of the performance of aero-engines, the temperature in front of the turbine is getting higher and higher. Under the condition that other conditions remain unchanged, for every 100°C (Celsius) increase in the temperature in front of the turbine of a turbofan engine, the maximum thrust of the engine can be increased by nearly 20%. . Therefore, various countries are competing to increase the working temperature before the turbine, from figure 1 It can be seen that there is still a certain gap between the temperature before the turbine in my country and the advanced countries in the world. [0003] If you want to increase the temperature before the turbine of the engine, you need the...
