Inconel 718 is a Ni-based superalloy, usually used for aircraft engine because of its high temperature properties and oxidation resistance. According to the current experiments, most experiments are done through the traditional manufacturing. Recently, the additive manufacturing, also called 3D printing, has been regarded as a new manufacturing that is used in the experiment. Different manufacturing causes the different orientation and segregation, and leads to different results with traditional manufacturing. Besides, the design for the heat treatment is always the point that researchers are looking for. The conventional method is homogenization and ageing, but some researchers have tried the direct ageing to find the differences. This paper focuses on the influence of temperature, time of the heat treatment and the effect of manufacturing method. It is concluded that the manufacturing method can influence the best choice of heat treatment. What is more, the additive manufacturing with high temperature homogenization and ageing is a good method in the experiment but it is hard to use in the industry now. Through the research of various factors, it is helpful to find a better method to improve the properties of Inconel 718 during the application.
