Material constitutive modelling of Fe-based, Ni-based and high-entropy alloys: Development of Simu-Mat 1.0

The application of material constitutive modelling in formative, subtractive and additive manufacturing processes was demonstrated by hot deformation of three alloys: (a) CoCrFeMnNi equiatomic high entropy alloy, (b) nickel-based alloy 625, and (c) 420 stainless steel. Phenomenological-, physical-,...

Description
Summary:The application of material constitutive modelling in formative, subtractive and additive manufacturing processes was demonstrated by hot deformation of three alloys: (a) CoCrFeMnNi equiatomic high entropy alloy, (b) nickel-based alloy 625, and (c) 420 stainless steel. Phenomenological-, physical-, and artificial neural network-based constitutive material models were then established utilizing the Simu-Mat 1.0. An average absolute relative error percentage (AARE%) of less than 10% was obtained. More specifically, stresses in the CoCrFeMnNi HEA, alloy 625 and 420 stainless steel, can be accurately simulated using Hensel–Spittel (AARE% = 5.93), Johnson–Cook (AARE% = 2.86) and Zener-Hollomon (AARE% = 8.13) constitutive models, respectively.
