ABSTRACT
In this chapter, where the motivation is to improve the brazing of difficult-to-join materials, three types of scenarios are envisioned. The methodology of dissolution and solidification is currently identified as transient liquid phase (TLP) bonding in the literature. Liu et al. and Ramirez and Liu modeled all three stages of TLP bonding those are including liquid formation, chemical homogenization within the liquid and isothermal solidification. Brazing can also be used to join nonmetals such as ceramics. It involves the use of a filler metal that joins base metals by heating the filler above its melting point, which is lower than that of the base metals that are being adhered. Brazing design is among the important, if not the most important, characteristics of a brazed joint structure. Brazing requires precleaning, and when brazing is done at terrestrial conditions, flux is used to prevent oxidation while the braze metal is heated mostly under controlled protective atmosphere.
