説明

From the standpoint of rate theory, the rate of solution of Cr-steel in liquid aluminium alloy was measured at 750-950°C<BR>The results obtained were as follows:<BR>1) The rate of solution of Cr-steel in liquid pure aluminium was 3.6°-19.4×10-6[cm/s] and in aluminium alloy (Fe 3%, Si 3.1%) was 1.81-17.0×10-6[cm/s].<BR>2) The value of activation energy for solution (EV) is equal to the sum of the value of activation energy for diffusion of iron in liquid metal (ED), heat of solution (ES) and the activation energy for viscosity of liquid metal (Eη).<BR>Values of-EV are equal to 30.1 and 32.4[kcal/mol], respectively.<BR>3) The controlling step of Cr-steel at solution process in liquid aluminium is the rate of diffusion of Fe atom in the diffusion layer.
