Structure Monitoring of the LaB$_6$–TiB$_2$ Composites

Abstract

The structure and properties of bulk and powder LaB 6 -TiB 2 composites as a promising material in solar energy converters have been studied by X-ray, metallographic, and pulsed excitation methods. The phase composition and defects of the composite's structure have been determined. The effect of heating-cooling cycles (20-1400°C) on the structure's characteristics of the composite's matrix phase is shown. The compatibility of the structure's analysis results by destructive (X-ray and metallographic) and nondestructive methods (pulsed excitation have been established). The capabilities of the pulsed excitation method for determining the composites structural characteristics and using it to control their quality under operating conditions are demonstrated.
