Iron-based metalloceramics functionally gradient material (FGM) was prepared by combustion synthesis casting under an ultra-gravity field through using thermite system with Fe3O4/Al/Fe-based cemented carbide. Multiphase kinematics characteristics and densification mechanism of cemented carbide particles in ultra-gravity field were explored. The results indicate that based on the Stocks rules; the effect on motion speed of particles in high-temperature melts is determined by density variation between the particles and melt; ultra-gravity coefficient; radius of particles; temperature and so on. Under a certain ultra-gravity coefficient condition; material density is related to bubble size and existing time of iron melt. On the top of the material; there are mainly two kinds of particles of ferrovanadium and ferrochrome; whose size will decrease along the direction of ultra-gravity field. However; ferromolybdenum mainly gathers in the interface between FGM and 45 steel. The most discrepancies of distribution characteristics for different particles are exhibited because of their difference of density and melting point. It leads to the gradient variation of hardness distribution for the FGM. © 2020; Science Press. All right reserved;
