Predicting adhesive properties of liquid-metal materials for fusion reactor blankets

A technique for calculating the surface energy and adhesion energy of single-component and multicomponent structural materials is suggested. It is based on a second-order model for an elastic continuum that assumes pair potential interaction between particles. Calculated values for the surface energy of single-component and multicomponent materials and also for adhesion energy in multilayer systems that are promising for liquid-metal blankets of fusion reactors are given. The effect of the component-to-component ratio on adhesion properties in a multilayer structure is analyzed for V-nCr-mTi alloy, which is the basic material of the lithium-vanadium blanket.
