Determination of distribution coefficients of admixtures in tungsten and molybdenum single crystals
Original language description
The aim of our experimental work was to study an influence of crystallization conditions on the segregation and structural characteristics of single crystals of low-alloyed molybdenum and tungsten alloys. Low-alloyed single crystals of W and Mo doped with Ta, Nb, W or Mo were prepared by the electron beam floating zone melting (EBFZM). The electron wave dispersive analysis was used for the determination of admixtures concentration on longitudinal sections. On the basis of chemical analysis were found the growth bands in these single crystals that are characterized by the sinusoidal wave of concentration profiles. Further the concentration relations in crystal and freeze zone in order to ascertain of effective segregation coefficients of alloying elements were determined. In order to evaluate relations between chemical inhomogeneity and structural defects and their influence on properties of single crystals there were experimentally investigated.
