Nanostructured soldered or brazed joints made with reactive multilayer foils

摘要: Self-propagating formation reactions in nanostructured multilayer foils provide rapid bursts of heat at room temperature and therefore can act as local sources to melt solder or braze layers join materials. This reactive joining method provides very localized heating the components cooling across joint. The results a fine microstructure material. scale material is dependant on rate joints which varies with geometries properties components. layer formed by melting furnace much coarser due slow rate. Reactive finer show higher shear strength compared those made conventional microstructure. It expected that may also have better fatigue joints.
