Abstract

The influences of roll pass design and THERMOMECHANICAL TREATMENT parameters on the development of surface cracks in hot rolled low alloy steel (41Cr4) bars were studied. Continuously cast slabs of (41Cr4) steel were solutionized at 1000°C and rolled down to 45 mm rounds. Various types of surface cracks in direction, length, depth and width were observed. It was found that the extent of defects depends on both mechanical and metallurgical factors. By a judicious design of roll pass it was possible to reduce extensively the number of surface cracks present after rolling. Also by controlling rolling parameters such as interpass time, deformation per pass and finish rolling temperature and deformation, the optimum hot rolling conditions were obtained. For each rolling schedule the microstructure and the mechanical properties were studied. Finally, for studying the effects of SURFACE DEFECTS on formability during the next hot forging process, cylindrical samples of rolled bars in different conditions Le: as rolled, as rolled and peeled, as rolled and machined were prepared and hot deformed between 30 to 60%. The influence of processing parameters and the extent of cracks on the forgeability was determined. The results are interpreted in the framework of classical nucleation and phase transformation theories.
