Název v původním jazyce

Microstructure and purity of NiTiZr-based alloys prepared by a plasma metallurgy process and vacuum induction melting

Popis výsledku v původním jazyce

Ni-45Ti-5Zr (at%) alloy was prepared by two different methods - by plasma and vacuum induction melting. Two samples were cut out both the ingots - the first out the edge and the second out the centre of the ingots. The aim was to confirm homogeneity of the ingots. Metalographical sections were used for photodocumenting of a microstructure, for verifying of chemical composition with EDS analysis and for statistic description of phases. Moreover, both the ingots were used for determination of C and O contents. In the both cases, structure was polycrystaline with a significant Zr segregation along dendrite boundaries. Chemical composition for the centre and the edge of the ingots was different only for the ingot prepared by plasma metallurgy. Unfortunately, both the ingots were contaminated with higher C and O contents. (C) 2019 TANGER Ltd., Ostrava.
