| Description
| - An advanced technology enabling the manufacture of stepped hollow products which are hard to manufacture using conventional technologies, and which at the same time contributes to the effective use of the material, is flow forming process. The purpose of our research was to evaluate the influence of the initial pearlite morphology on the formability of a low-alloyed steel workpiece using this technology. A stepped hollow shaft made from low-alloyed steel 16MnCrS5 was formed by flow forming process. Tubes with various initial technologies and mechanical properties were used as workpieces. The influence of the initial morphology of pearlite in the workpieces was investigated, not only in relation to formability but also on relation to the size of the reduction and the quality of the internal and external surfaces of the resulting product. The changes in microhardness were evaluated on the finished part, which provides information about the distribution of deformation across the wall of the workpiece. Mechanical properties were measured at selected sites on the part. Finally, the correlation betwenn structure, ultimate strength, microhardness HV 0.2 and size of reduction of the initial workpiece was evaluated. From these results it is possible to design a suitable pearlite morphology for achieving a high quality workpiece.
