“…According to the experimental results of Cai et al [39] and Sudararaman et al [4], the δ-phase precipitates directly from the austenite or it precipitates by nucleation at grain boundaries followed by the growth extending into the grains when isothermal aging temperature is above 900 o C.…”

Grain boundary precipitates in Inconel 718 and ATI 718Plus are important to control during hot working processes, since they can control the grain size. Precipitating excessive or insufficient amounts can be detrimental to the final component. Therefore, it is important for manufacturers to understand the formation and kinetics of grain boundary precipitation and the effect this has on mechanical properties. This review considers the background of grain boundary precipitation, including the effect of the thermal stability of γ and γ phases. In addition, the effect of stress on the grain boundary phases and their precipitation kinetics in different conditions are also included. Also, the impact of grain boundary precipitation on the mechanical properties is explored. ARTICLE HISTORY

“…Delta phase in ATI 718Plus alloy is thought to play a role similar to that in alloy 718, namely as a grain boundary precipitate phase that helps provide resistance to notch failure and high temperature embrittlement [8,9]. Delta phase in alloy 718 is also used during hot working to pin grain boundaries and produce a finer average grain size [10].…”

ATI 718Plus ® alloy relies upon grain boundary precipitation of the delta phase in order to achieve good resistance to notch failure. Delta phase precipitation can occur when forging at subsolvus temperatures or during solution annealing. Precipitation of delta phase during solution annealing can be affected by the interaction of forging temperature and strain during hot working whereby the combination of high forging temperature and low strain can result in unsatisfactory delta phase precipitation. Additionally, delta phase precipitation can be affected by exposure to supersolvus temperatures after forging is complete. This paper describes the effect of thermal mechanical processing history on delta phase precipitation in ATI 718Plus alloy and provides guidance on best practices to achieve optimum microstructure.
