Abstract

The aim of the project was to apply the currently available tools for the simulation of the heat treatment processes to achieve accurate knowledge of the involved processes to allow the end-products to be influenced.

For C-Mn steels, Ti or Nb microalloyed steels, and TRIP steels, the influence of various hot-rolling, coiling or annealing conditions were investigated by computer simulation as well as by processing steels in the laboratory or pilot plants. For different production processes, the development of the microstructure was calculated. Special attention was given to the part that the precipitation of microalloying elements plays during thermomechanical treatment. The mechanical properties of steels from the pilot production were measured and compared with the results of the calculations. The transformation behaviour was calculated and the results compared with dilatometer tests.

The derived results can be used to improve the accuracy of the simulation of hot-rolling processes. This is achieved mainly by the extension and observation of the transformation and precipitation processes. Computer simulations as tools for the study of the heat treatment processes can provide the necessary knowledge of the involved processes to allow the resulting steels to be influenced. Therefore, diverse mechanical properties can be adjusted for the same chemical composition by suitable selection of the production parameters and the potential properties can be better exploited, leading to a reduction in the types of steel. el.
