摘要

The effects of CeCl_3-containing fluxes on RE element loss, the high temperature mechanical properties, microstructure and corrosion properties of magnesium alloy containing RE have been studied. The results showed that a certain amount of CeCl_3 in purification fluxes restrained the reaction between the Ce element and fluxes to decrease the loss of Ce in alloys. With the flux containing 9% CeCl_3, the loss rate of alloy element Ce can be reduced from 26.9% to 3.4%, and the σ_b and 5 of the alloys at 150°C counld be improved from l60.9MPa and 6.2% to l76.5MPa and 7.9% compared with that of conventional MgCl_2-containing flux , respectively. Besides, the coarse β phase and rod-like RE phase were refined effectively by CeCl_3-containing fluxes.
