| Abstract Scope |
The growing demands for elevated efficiency in the solar energy industry led researchers to focus on the development of functional solar absorber tube material in concentrated solar power (CSP) systems when molten salts are adopted as the heat transfer fluid. In this study, Inconel 718 was enhanced with boron to achieve a higher solar absorptivity in the visible light spectrum and a lower long-wave emissivity while maintaining a high corrosion resistance. Combined with an additive manufacturing (AM) method, the boron composition exceeded the traditional manufacturing limit of 60 ppm without microstructural defects. The boron-enhanced Inconel 718 exhibited a high solar absorptivity of nearly 90 % while maintaining a high thermal cycle fatigue resistance after thermal cycling treatment between 550°C and 720°C. The provided microstructure-property map within the range of boron composition up to the manufacturing failure point delivers high potentials of functional AM-printed alloy material in CSP applications. |
