Abstract

The rates of dissolution V of rotated steel rods (2-10mm ƒ) in molten Al (775°C), Zn (600°C) were measured.
Experimental results were examined in the light of diffusion theory and it was found as follows:
1) At the lower stirring speed (Re<5×102), the rate controlling mechanism of the dissolution is Fe-diffusion in liquid metals and the obtained data can be correlated to the formula:
_??_
2) At the higher stirring speed (Re<103), the rate controlling mechanism of the dissolution depends on both processes i.e. Fe-transfer from solid alloy surface to liquid metal and Fe-diffusion in liquid metal, simultaneously.
So, above equation is not applicable to these high stirring conditions.
