Application of FEM to Hot Continuous Rolling Process for Inconel 718 Alloy Round Rod Original Research Article

A finite element model for coupled thermo-mechanical analysis has been developed in hot continuous rolling process for Inconel 718 alloy round rod with diameter of 45 mm. The stability of this alloy is discussed by integration of FEM and processing map reported in literatures. The result shows that the stability of Inconel 718 alloy is analyzed effectively during that process and good stability appears as the initial temperature is 960°C and the initial velocity is from 0.15 to 0.45 m ·s−1 or the initial temperature is 980°C and the initial velocity is from 0.15 to 0.25 m · s−1.
