Influence of element Cu on hydrogen content in superheated aluminum melt

The hydrogen content in molten Al Cu alloy increases remarkably when the temperature of the melt rises to about 780 ℃. The effects of alloying element are theoretically analyzed in terms of Wagner interaction parameter. Furthermore, analyses indicate that the alloy element Cu plays an important role in the hydrogen content in superheated Al Cu alloy melt below about 780 ℃. The conclusion is drawn that the degree of gassing in molten Al Cu alloy is bound up with the properties of oxide film of Al alloy melts. The results make it clear that the hydrogen content in the molten aluminum reduces with increasing element Cu dissolved in aluminum melts at the same temperature. [
