Abstract

High temperature alloy GH4169 has excellent mechanical and chemical properties, and has advantages such as fatigue resistance, radiation resistance, and oxidation resistance. It is widely used in aerospace and other fields, but its high hardness makes it a difficult to machine material. Electric discharge machining technology is suitable for processing various difficult to machine materials, but due to the complex discharge process and multiple discharge parameters, it is difficult to form effective process regulations. Modeling the discharge machining process using ANSYS, and conducting temperature field simulation research on the erosion mechanism of GH4169 in electric spark pulse discharge. The results show that there is a positive correlation between voltage and temperature field. Increasing the voltage has a significant increase in the central temperature of the discharge channel, and increasing the voltage can increase the erosion efficiency.
