Artificial neural network modeling to evaluate and predict The deformation behavior of type 304L stainless steel during hot torsion is investigated using artificial neural network (ANN). Torsion tests in the temperature range of 600-1200^oC and in the (maximum surface) strain rate range of 0.1-100s^-^1 were carried out. These experiments provided the required data for training the neural network and for subsequent testing.
Significant amounts of blast furnace slag (BFS) are generated daily as by-product from iron and steel industries.
