Abstract

V prispecku predstavljamo rezultate raziskovalnega dela, s katerim smo želeli preveriti možnosti določitve vplivnih parametrov pri usmerjenem strjevanju zlitin s kvantitativno analizo lite mikrostrukture. Pri vzorcih usmerjeno strjene zlitine Cu-Cr-Zr smo z različnimi metodami kvantitativne analize izmerili geometrijske parametre mikrostrukture (primarno in sekundarno dendritno razdaljo ter volumski delež evtektika) in ob upoštevanju analitičnih izrazov, ki podajajo razmerja med geometrijskimi parametri mikrostrukture ter parametri strjevanja, slednje tudi določili. Primerjava tako določenih parametrov strjevanja z eksperimentalno izmerjenimi vrednostmi je pokazala dobro ujemanje.

Secondary title: Characterization of directional solidification in a Cu-Cr-Zr alloy with quantitative microstructural analysis
Secondary abstract: In this paper the results of our research on tahe possibilities for defining the influencing parameters that describe a directionally solidified microstructure using quantitative microstructural analysis are presented. The geometrical microstructural parameters (primary and secondary dendrite arm spacing and the eutectic volume fraction) were measured with different methods of quantitative analysis on samples of directionally solidified Cu-Cr-Zr alloy. The solidification parameteres were then calculated considering the relations between solidification and geometric microstructural parameters. The composition shows a good agreement between the calculated solidification parameters and the solidification parameters determined by experiment.
