Influence of Extrusion Temperature on Microstructures and Mechanical Properties of Bi2O3-Coated Al18B4O33 Whisker Reinforced Al Composites
Extrusion experiments have been carried out on Bi2O3-coated Al18B4O33 whisker reinforced aluminum matrix composite. The effects of the extrusion temperature on the microstructures, the formability and the mechanical properties of ABOw reinforced aluminum (ABOw/Al) composites with and without Bi2O3 coating were investigated. The results show that the steady-state extrusion load and the probability of whisker fracture of the extruded two composites decrease with the extrusion temperature increasing. The mechanical properties of the composites attain highest values at extrusion temperature of 673K.
