主　　题：Biodegradable Magnesium alloy Porous HA Composite Squeeze casting 

摘      要：AZ91/HA composite was prepared by AZ91 magnesium alloy and porous HA using squeeze casting method. The microstructure and mechanical property of the AZ91/HA composite were studied. The results show that the molten AZ91 alloy completely infiltrated the preform without destroying the porous structure of the HA preform. The compressive strength of AZ91/HA composite increased significantly compared with that of the porous HA. The immersion test indicated that AzgI ahoy shows a lower corrosion resistance and is easier to be corroded in comparison with HA.
