Effect of Mini-Thixoforming Parameters on Microstructural Evolution in Low-Alloy Steel

Popis výsledku v původním jazyce

The ever increasing demands on the complexity of product shapes and the required material properties drive the development of new technologies. One of these technologies is mini-thixoforming. Thanks to the specific process conditions, near-net-shape products can be made in a single forming step. However, as the process is technically demanding, the use of medium and low-alloy steels has not been explored yet. In the present experiment, the 30MnVS6 low-alloy steel was used. In its initial condition, it has a ferritic-pearlitic microstructure. The initial set of parameters of processing was proposed on the basis of calculation. These parameters were then optimised experimentally. The microstructure of the products consisted of martensite. Consequently, the feasibility of producing bainitic microstructure which offers higher toughness was explored. Controlled cooling was chosen as the technique to obtain bainite. The controlled-cooling process simulated forming in a pre-heated die.
