Abstract:

Computer aided design of the manufacturing technology for the fasteners made of bainitic steels is the objective of the paper. Main features of the new generation of bainitic steels are discussed. Rheological and microstructure evolution models for selected steel were developed. The models were implemented into the finite element code for thermalmechanical simulations of metal forming processes. The particular objectives of the work were twofold. Simulations of various variants of manufacturing chain were performed first. Main operations, which were considered, include: hot rolling of rods and wires, cooling after hot rolling, cold drawing to reduce the diameter and forging in three operations without heat treatment. The best manufacturing chain was selected on the basis of numerical simulations. Industrial trials were performed for the selected cycle and the efficiency of this cycle was evaluated.
