The paper describes the results of structure and properties tests of flat bars made of alloy WE43 obtained in the process of extrusion with the use of KOBO method. An analysis of structure changes was conducted both in initial state and after plastic deformation. A quantitative analysis of the material was also conducted with the use of METILO program. The paper also presents results of mechanical tests marked in the uniaxial tensile testing in room temperature and in elevated temperature for achieved flat bars. Fractographic tests were conducted after tensile test in order to determine the mechanism of cracking.
