Abstract  

By means of quantitative analysis method, gas solubility, gas bubble nucleation condition, nucleation work, critical nucleation radius, and nucleation rate in centrifugal casting liquid metal filling and flow process are studied. The results show that with increasing the centrifugal radius and angular velocity, gas solubility as a gradient vector in centrifugal field, gas bubble nucleation work, and critical nucleation radius increase, but gas bubble nucleation rate decreases. Meanwhile, the effect of the centrifugal radius and angular velocity on gas solubility and gas bubble nucleation is more significant with their increasing. Therefore, porosity can be reduced through increasing the centrifugal radius and angular velocity in centrifugal field.

Key words:  metallic materials      centrifugal casting      theoretical analysis      gas bubble      nucleation
