Turbine Wheel Casting Pouring Process Parameters Improvement

Popis výsledku v původním jazyce

Mechanical characteristics of the creep-resisting alloy IN 713 LC depends on its content and material purity, furthermore on the structure and structural non-homogeneities. Significant influence on the material properties, for its usage, has the way of crystallization (exogenous and endogenous/ from walls or with pulpy solidification from the centre of the casting), temperature (influences the direction and magnitude of the growth of dendrites), vaccination secured using cobalt aluminate (formation of nucleation germs). The aim was to realize the tests on the samples. Casting process and sequential detail grain structure study. The samples were analysed by RTG and FPI method, in the form of a compact material. The samples were cut. Interesting data were obtained in these areas: grain size and structure with dependence to the casting temperature, the shell annealing temperature and packing by exothermic padding – Sibral, on the specified places defined with the insulation thickness to ensure surface controlled crystallization in the casting.
