Inconel 718 alloy is widely processed into various parts and used in various environments due to its excellent properties. Correspondingly, the Inconel 718 alloy used in different environments needs appropriate processing technology, and the microstructure and properties of the Inconel 718 alloy obtained by different processing technology are also different. Therefore, it is of great significance to formulate a reasonable processing technology for the application of Inconel 718 alloy.
Deformation is an important means to optimize microstructure and improve properties of nickel-based alloys. The past research on Inconel 718 alloy mainly focused on hot compression and creep: however, the effect of cold deformation on the microstructure of Inconel 718 alloy is rarely reported. In particular, the effect of cold rolling on the precipitation behavior of Inone1 718 alloy mesophase remains controversial.
In addition, in the past, the means of studying the precipitation behavior of the mesophase were relatively simple, limited to XRD and metallographic observation, and further in-depth research is urgently needed. Electron beam welding, as a high-energy-density fusion welding technology, has been widely used in the connection of Fe-Ni-based alloys. Compared with traditional welding technology, electron beam welding has the advantages of narrow weld pool area and heat-affected zone, and small deformation due to the lower energy input of electron beam welding.
Furthermore, due to its high energy density, faster welding speeds can be achieved. However, the segregation of interdendritic Nb leads to the formation of Laves phase and the formation of microcracks in the heat-affected zone, which are the shortcoming of electron beam welding.
At present, many studies pursue the excellent microstructure and properties of weldments by changing the energy input and post-weld heat treatment. The base metal and welding speed are also important factors affecting the weldment. In this paper, the influence of base metal and welding speed on electron beam welding of Tncone1 718 alloy has important practical significance for optimizing the performance of weldment.
Inconel 718 is a high-strength heat-resistant nickel-based alloy with excellent high-temperature strength, high-temperature hardness and corrosion resistance. It can work for a long time under high temperature conditions. It has been widely used in the aerospace industry, turbine engines and related industries in the aviation industry.
Manufacture of parts, analyze the mechanical properties, microstructure of Inconel 718 and its influence on cutting performance, and carry out relevant experimental verification. The effect of wear, the test results show that the carbon content in Tncone]718 plays a very important role in the wear of the tool flank. Correctly cutting the knife during the process and causing subsequent grain damage to reduce the machinability of the material.
