Název v původním jazyce

Segregation behaviour of niobium and its influence on structural characteristics of molybdenum single crystals prepared by electron beam floating zone melting

Popis výsledku v původním jazyce

When preparing quality single crystals of low-alloyed alloys on the base of molybdenum as well as other high melting metals, it is necessary to investigate influence of alloying elements on the single crystal structural, mechanical and physical properties and their behaviour during crystallization under given conditions. The aim of the present work was to evaluate the influence of niobium on structural perfection of single crystals of molybdenum and its behaviour from the view of segregation characteristics. For this purpose single crystals of low-alloyed alloys Mo-1.5 at.% Nb were prepared by the electron beam floating zone melting under various conditions of crystallization (1, 3, 5 mm/min). These single crystals were submitted to metallographical, chemical and X-ray analyses. It was found that alloying of molybdenum single crystals with niobium resulted in disintegration of block structure, i.e. reducing the sub-grain dimensions and increasing the angle of disorientation of their bo
