An Investigation into the Dynamic Recrystallization (DRX) Behavior and Processing Map of 33Cr23Ni8Mn3N Based on an Artificial Neural Network (ANN)

Abstract: Based on an 33Cr23Ni8Mn3N thermal simulation experiment, the application of an artificial neural network (ANN) in thermomechanical processing was studied. Based on the experimental data, a microstructure evolution model and constitutive equation of 33Cr23Ni8Mn3N heat-resistant steel were established. Stress, dynamic recrystallization (DRX) fraction, and DRX grain size were predicted. These models were evaluated by a variety of statistical indicators to determine that these models would work well if applied in … Show more

“…In subsequent iterations of the algorithm, a different set of independent variables is checked for which the neural network is trained. The genetic A common solution is to calculate the relative importance of the input variables [35,47,48]. The coefficient value for each independent variable can be calculated based on the weights of connections of the input and hidden layer neurons.…”

“…In their method, they used artificial neural networks and the ANSYS FLUENT software. Cai et al [47] developed a neural model for calculating the grain size, stress and volume fraction of the recrystallized phase in the heat-resistant alloy steel. The neural model was used to model the thermomechanical treatment process by the finite element method.…”

“…As previously reported [1,6], DRX is the main deformation characteristic of the β phase in the hot compressed Ti-55511 alloy. Generally, the DRX mechanism can divided into CDRX and DDRX [42,43]. CDRX is related to the formation of subgrains while DDRX is related to the nucleation-growth of strain-free new grains [44,45].…”
