| Development of advanced lightweight nanostructured steel and its manufacturing-easy heat processing for ultrahigh-strength applications | |
| Program: | SRDA |
| Project leader: | Prof. Ing. Iefremenko Vasyl, DrSc. |
| Annotation: | The project is aimed at the development of novel cost-saving steel for ultrahigh-strength applications (ultimatetensile stress not less than 2000 MPa under acceptable ductility/impact toughness) and the technology of its hotdeformation and heat treatment which can be easily integrated into the production lines present at the metallurgicalplants. The steel will not comprise the expensive alloying elements (Ni, Cr, Co, Mo, V), in contrast, due to using thecheaper elements (such as Mn, Si, and Al which are lighter than Fe) it will acquire the lightweight feature. The mainobjective will be reached through the formation of a multi-phase "smart" structure that can respond to the externalload by TRIP/TWIP effects leading to self-strengthening and stress relaxation. This structure will be developed bymeans of appropriate chemical composition selection and the novel processing route design based on newtechnological approaches and solutions allowing for a reduction of the processing duration, energy consumptionand using conventional "easy-in-operation" equipment. The results of the project will have a direct positive impacton the metallurgical sector as well as on the users of ultrahigh-strength steels (machine-building, constructionsector) which will benefit from the reduction of steel cost and use the production-easy (time-saving) processingtechnology. |

| Development of Fe-Si alloys with double-oriented cube crystallographic texture | |

| Annotation: | The scientific research project aims to develop Fe-Si electrotechnical steels with excellent magnetic induction isotropy and low watt losses. The project\’s concept is based on increasing the intensity of the double-oriented cube crystallographic texture within the sheet plane by inducing abnormal growth of ferrite grains through mechanisms involving inhibitory, diffusion-controlled, and deformation-induced grain boundary movement in the primary recrystallized microstructural matrix. To achieve a coarse-grained microstructure with a significant representation of grains possessing the required cube crystallographic orientation, Fe-Si steels will be designed using an original chemical concept. In these steels, innovative thermo-chemical and thermo-mechanical processing will create a complex of VC nanoparticles with a gradient distribution along their thickness. This will enable the abnormal growth of grains with cube texture components (111)[0vw] during dynamic heat treatment. The resulting microstructural and textural state of the steels will form the basis for achieving magnetic properties isotropy with relatively low wattage losses and a high isotropic value of magnetic induction. The output of the project will be, in addition to the knowledge obtained from basic research, a proposal for a technological procedure for the preparation of such a microstructure. |
