Abstract

The inhibition effect of inclusion particles and soluble elements on the austenite grain growth has been studied in Fe-0.05% C and Fe-10% Ni alloys deoxidized by Mn (1.0%) - Si (0.2%), Ti (0.05%), Mg (0.10%), Zr (0.08%) or Ce (0.12%). It is found experimentally that total surface area of grains per unit volume, which is in inverse proportion to the grain size, increases linearly with increasing the surface area of particles per unit volume. However, the size of grains in metal with high content of soluble Zr and Ce is significantly smaller than the predicted value from the effect of particle pinning. The additional effect of soluble Zr and Ce on austenite grain growth becomes more significant with an increase of these contents in alloys. An effect of nonrandom dispersion of particles on grain growth is also estimated and discussed.
