Abstract
The DP_builder software, which was developed to design the best continuous annealing technology for DP steels in a fast and efficient way, is presented in the paper. The key components of the system, including models of phase transformations during heating and cooling stages, are described first. Following this, major principles, features and implementation details of the system are presented. Main functionalities provide possibilities of simulation of microstructure evolution during various thermal cycles and capability to design the best technological variant. Additionally a database, which stores material and technological information for all previously analyzed cases, was designed and incorporated in the system. Finally, graphical user interface was added to make the system easily accessible and user friendly.
