In order to study the dissolution behavior of solid metal in a melt, experiments have been conducted in steel plate and aluminium melt. The experimental parameters were the position and orientation for steel plate in the melt, and dipping time in the aluminium melt.
The results of studies are summarized as follows.
At the initial state the dissolution rate is increased slowly, and then reached a steady state. After 60 minute, the rate is become slow again. It is suggested that the rate controlling step in this dissolution process is mass transfer process from the solid/luquid interface to the melt by the thermal and copositional convection.
The reaction products during th process are FeAl_2 and FeAl_3. The dissolution rate is remarkably fast near the melt surface.
