Analysis of Hot Tensile Fracture and Flow Behaviors of Inconel 625 Superalloy.

Article Synopsis
- The study investigates how Inconel 625 alloy behaves under high temperatures (700-800 °C) and specific strain rates (0.005-0.01 s) during tensile testing, focusing on deformation and fracture mechanisms.
- It identifies that ductile fracture occurs mainly through the formation and merging of microvoids and finds that increased temperature and lower strain rates lead to more intergranular fractures due to dynamic recrystallization.
- Additionally, two predictive models for tensile behavior are compared, with the particle swarm optimization-artificial neural network (PSO-ANN) model performing better than the traditional Arrhenius model, demonstrating higher accuracy and lower relative error.
