WitrynaGold–Aluminum Intermetallic Formation Kinetics. Abstract: Au-Al intermetallic compounds (IMC) grow laterally (Al-rich phases) in a Fickian fashion with an activation energy of 1.0 eV, but vertical IMC thickness (Au-rich phases) grows functionally as a power law on time with a sub-Fickian exponent of 1/4, which is substantially smaller … Witryna60.9 kJ/mol. The thin Al metallization could be an important factor in affecting the rate of formation of Cu-Al intermetallics due to the limiting material effect. The intermetallic growth mechanisms of Au on Al pad has been reported to a much lesser extent [3], and the activation energy of Au has not been widely published.

WitrynaThe time compensated IMC thickness in FSW was larger than that in the other joining methods. This is because three factors of fresh surface, stored strain and plastic flow were strongly affected the formation mechanism of IMC. However, the amount of IMC was significantly small because the welding time was very short. It is therefore …
