High performance PbLi blanket

Abstract: A novel blanket concept is described. The proposed design Is a dual coolant concept based on ferritic steel as structural material using helium to cool the first wall. The temperature of the entire steel structure is maintained below the 550/spl deg/C limit. The breeding zone is cooled by circulating the liquid metal breeder to external heat exchangers. Flow channel inserts are employed in the poloidal liquid breeder ducts, serving both as electrical and thermal insulator between the flowing liquid metal and the steel structure. In this way, a liquid metal exit temperature of about 700/spl deg/C is achievable, allowing either an advanced Rankine steam cycle or closed-cycle helium gas turbine (Brayton cycle) as the power conversion system. A gross thermal efficiency of about 45% can be achieved with either system.

Recoverable Liquid Metal Paste with Reversible Rheological Characteristic for Electronics Printing

Abstract: Gallium-based liquid metals are applied in the fabrication of soft electronics because of their conductivity and flexibility. However, the large surface tension and weak adhesion of liquid metals limit the available printing substrates. Recent researches indicate that amalgamating metal particles can turn liquid metal from fluid into a paste which has superb electrical conductivity, plasticity, and strong adhesion to substrates. In this work, a recoverable liquid metal paste was made by mixing eutectic Ga–In alloy and nonmetallic SiO2 (quartz) particles (Ga–In–SiO2 paste, called GIS). GIS has excellent conductivity and printable properties similar to those of previously reported liquid metal pastes. Furthermore, the bonding between Ga–In alloy and quartz particles is reversible. In acidic or alkaline solution, Ga–In alloy can be separated from quartz particles and agglomerated to bulk by stirring. Moreover, the study of the mechanism of adhesion behavior suggests that extruding fresh liquid metal droplets...

Liquid Metal Equation of State Based on Scaling

Abstract: Experimental data on the equation of state of liquid metals are summarized to show that a corrected entropy of melting can be taken as a constant for all metals and that the specific heat in the liquid has a universal dependence on the ratio of the temperature to the melting temperature. From these correlations, together with the Lindemann law for melting, an approximate equation of state for liquid metals is developed.

Fundamentals of Liquid Metal Corrosion

Abstract: The corrosion of structural metals in liquid metals is for the most part the result of solubility of the various constituents of the metal or alloy in the liquid metal. The manner in which this solution manifests itself gives rise to many types of attack, ranging from a simple solution type attack to a deep intergranular attack with the preferential leaching of one constituent of an alloy. Examples of the many types of corrosion experienced with solid metalliquid metal systems are illustrated. The role of impurities on the corrosion is discussed. In addition to the solution stage, which would soon disappear in a static one metal system on reaching a solubility limit, the corrosion of metals can be continued through the removal of materials from solution in the liquid metal with a temperature gradient or by dissimilar metal tranfer. The transfer of metal in a plumbing system by the mechanisms of mass transfer—temperature gradient and dissimilar—will greatly increase the amount of corrosion as comp...
