Název v původním jazyce

Impact of conditions of directional crystallisation by bridgman method on physical and metallurgical characteristics of Ni3Al

Popis výsledku v původním jazyce

Directional crystallisation enables influencing of structure and properties of the final product. It is possible to control by this process forming of shrink holes, influence grain size and manner of their growth. Samples of Ni-Al alloys of various chemical composition were used for measurement. 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 on special equipment in Vladimir (Russia). The cast pieces were inserted into electro-corundum tubes with specified apex angle. Various rates of directional crystallisation were used for verification of the most suitable conditions for obtaining of homogenous and mono-crystalline 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 w
