Influence of density of dislocations on selected mechanical properties of directionally crystallised Ni3Al based alloy

Popis výsledku v původním jazyce

The paper is oriented on investigation of influence of deformation behaviour of Ni3Al based alloy in dependence on chemical composition and conditions of preparation with focus on structure. Density of dislocations was determined in deformed and non-deformed condition of Ni3Al based material. The samples containing 22 at.% of aluminium and 25 at.% of aluminium were chosen for analysis. All the samples were used in directional state. The samples were submitted to tensile tests, metallographic analysis. They were afterwards used for manufacture of thin foils for investigation by method of transmission electron microscopy. The targets were prepared with use of parts of bars after tensile test. A dependence on selected mechanical properties was establishedfrom the ascertained facts. Dependence of ductility on the ratio of dislocations density in deformed and non-deformed parts appears to be highly remarkable.
