| Popis: | The goal of the current work was to check the possibility of the use of various modelling methods of multicomponent systems calculations, for a design of optimum composition of a new high entropy alloy. Three modelling methods were utilized and discussed in the light of production of an alloy with solid solution of BCC and FCC phases as well as Laves phase what should provide unique properties of this alloy – compared to already proposed high-entropy alloys. The amount of Laves phase should be however strictly controlled and limited due to their low ductility at room temperature. Based on the calculations, optimized composition of Fe19Mn38Ni30Nb7Al3Ti3 system was designed and produced using arc melting. After solution heat treatment the produced specimen was tested using XRD. Based on the comparison of the results, conclusions regarding the capability of presented modelling methods for a design of high entropy alloys for metal forming are drawn. |
