Název v původním jazyce

Structural and micro-structural analysis of directionally crystallised inter-matallic compound Ni3Al realised by TEM

Popis výsledku v původním jazyce

Method of directional crystallisation was used for modification of their as-cast structure, as this method can influence structure and therefore also properties of final material. The samples were prepared by casting in vacuum induction furnace. Cast rollers with diameter 10 mm and length 95 mm were afterwards directionally crystallised by Bridgman method with vertical arrangement. Part of samples was prepared at the Department of non-ferrous metals, refining and recycling at VŠB-TU Ostrava, and remaining part of the samples was melted into electro-corundum tubes with specified apex angle on special equipment in Vladimir (Russia). Various rates of directional crystallisation were used for verification of the most suitable conditions for obtaining of homogenous structure. Suitable samples were adjusted by turning to tensile rods, which were then used for tensile tests with measurement of acoustic emissions. For these tests there were used short tensile rods of round section with length
