ferritic-martensitic.
Second, the forward, reverse, and microstructural models are combined to form an integrated design model.
The reverse model takes targeted performance metrics as inputs to propose an initial design scheme for
compositions and processing. The microstructural model then predicts the microstructural attributes of the
aforementioned design scheme. If the predicted microstructures meet the requirements, the design scheme
is accepted. If not, the reverse model is retrained, and the process is repeated until a suitable design scheme
is found. The forward model then predicts the performance of the accepted design scheme, which is
compared to the targeted performance. If the performance criteria are not met, retraining and iterations
continue until a satisfactory design scheme is founded.
