Material and technological modelling of closed-die forging

Original language description

In the forging industry, as in other sectors, opportunities are sought for a continuous improvement in the manufacturing productivity. The solution can be found predominantly in optimizing the existing manufacturing processes or developing new ones. However, suspending the production in order to verify optimization proposals often results in substantial financial losses to the company. The present paper describes a design of a comprehensive material/technological model of a production sequence of real-world forging, including the heat treatment in continuous furnaces. A forging used in automotive applications is made of the C45 steel by closed-die forging. A material/technological model of this forging was developed using data gathered in the real-world forging production and with the aid of a FEM simulation. Good agreement between the specimen processed according to the model and the real-world forging was confirmed with a metallographic observation and tension testing. In both cases, the microstructure consisted of ferrite and pearlite. The ultimate strength of the forging was 676 MPa and its elongation reached 28 %. In the material processed according to the model, the ultimate strength was 655 MPa and the elongation level was 32 %. The results will be used as the basis for the material/technological modelling in an effort to develop and optimize a controlled cooling sequence to replace the existing heat-treatment process.
