Simulation of structure formation of austenitic steel weld

摘要

An integrated model of phase transformations is proposed, which unites the model of changes in the temperature fields of the workpiece during welding and subsequent cooling, as well as a simulation model of phase transformations that occur during cooling of the steel. The developed method allows predicting the amount of residual δ-ferrite in the structure of the weld of austenitic stainless steel, which is necessary to justify the welding conditions.
