Product Description

GH15 overview

GH15 alloy is a high-performance iron-nickel-based superalloy developed in China. The austenite is compound strengthened with about 10% of the total amount of tungsten, aluminum and niobium rich in my country, so that the alloy maintains high plasticity and excellent oxidation resistance. At the same time, the thermal strength is greatly improved, and it also has good process performance such as stamping, welding and thermal processing. Its comprehensive performance level is comparable to that of Hastelloy X, a nickel-based alloy widely used in Sumerian. The thermal strength is slightly higher than that of the above alloys, and it is suitable for the manufacture of aero-engine combustion chamber parts that work below 900-950 °C.

GH1015 application overview and special requirements
Aero-engine combustion chamber parts have been manufactured and put into mass production. After long-term use at a temperature of 700-900 °C, there is a certain hardening phenomenon, which reduces the room temperature plasticity; the oxidation resistance at high temperature above 1000 °C is slightly worse than that of nickel-based alloys for similar purposes.

GH1015 Formability
1) During forging, the furnace temperature should not be higher than 700ºC, the heating temperature should be 1160ºC±10ºC, the opening forging temperature should not be lower than 1000ºC, and the final forging temperature should not be lower than 900ºC.

2) Hot rolling: The furnace temperature for hot rolling of the bar is not higher than 700 °C, the heating temperature is 1150 °C ± 10 °C, the rolling temperature is 1050 °C ± 10 °C, and the final rolling temperature is not lower than 980 °C. During hot rolling, the heating temperature is 1150-1170ºC, and the final rolling temperature is not lower than 900ºC.

3) Cold forming performance: The plate in the supply state has good plastic parts, so the forming process is generally carried out at room temperature, but the power required by the forming equipment is slightly larger than that of austenitic stainless steel. When making parts in multiple forming processes, solution treatment is required after each cold forming process. Before forming, the surface of the sheet is coated with nitro varnish.

At present, in the more advanced foreign aero-engines and civil gas turbines, most of the combustion components are made of Hastelloy X, a nickel-based alloy with higher performance. These alloys are solid solution strengthened with a large amount of tungsten molybdenum element, so that the alloy maintains high plasticity and excellent oxidation resistance, and at the same time greatly improves the thermal strength, and also has good process performance such as stamping and welding, so it burns at high temperature. Parts have been widely used, such as alloy is one of the most used superalloys in the production of jet engines in the United States. In my country, the wide application of alloys in aero-engines fully demonstrates that iron-based superalloys can fully meet the requirements of combustion chamber components. Therefore, on the basis of GH140 alloy, we further alloyed it, increased the content of tungsten and indium in the alloy, determined its optimal ratio, and added niobium to austenite for composite solid solution strengthening, and the development was successful. New iron-based superalloys. Its thermal strength reaches or even exceeds the level of the above two nickel-based alloys, but at the same time it retains the characteristics of high plasticity, good thermal fatigue and process performance, and can be used as a substitute for these nickel-based alloys. Aeroengine combustion chamber components operating below 950°C.

This material is used in the engine to increase the outlet temperature of the combustion chamber, which is conducive to improving the thrust of the engine, eliminating the original crack failure, prolonging the life of the engine, reducing the weight of the components, improving the thrust-to-weight ratio of the engine, and improving the performance of the engine. Substituting materials for GH30, GH39 and GH44 can save a lot of nickel per ton. It shows that it is economically beneficial, and it is also successful in technology and use.

This material can obtain better welding quality and machining quality without adding special equipment, and can process qualified products that meet the design requirements, indicating that its manufacturability is also good.

The above is the introduction of GH1015 (GH1015) superalloy material
