Abstract

A pure aluminum matrix composite reinforced by Bi₂O₃-coated aluminum borate whisker was fabricated by a squeeze casting method. The mass ratio of Bi₂O₃ to whisker is 1-30. The interfacial reaction between Bi₂O₃ coating and aluminum takes place during casting process. Deformation behavior and formability of ABOw reinforced aluminum (ABOw/Al) composites with and without Bi₂O₃ coating were investigated by the extrusion deformation at 400°C. The results show that the steady-state extrusion load and the probability of whisker fracture of extruded ABOw/Al composite with Bi₂O₃ coating are lower than those of extruded ABOw/Al composite, and its surface quality is better than that of extruded ABOw/Al composite. Evaluation of the tensile properties shows that the extruded ABOw/Al composite with Bi₂O₃ coating have the ultimate tensile strength and yield strength with 0.2% superior to those of ABOw/Al composite.
