Aluminum alloy matrix composites containing 1 to 30 wt pct of fibrous and
particulate nonmetals varying in size from 0.06 μm to 840 μm were fabricated.
The composites were cast into cylindrical molds for friction and wear tests, hot
extrusion and tensile tests. The distribution of the nonmetals in the cast
ingots was homogeneous. Friction and wear tests were done on a pin (52100
bearing steel) and... hiện toàn bộ
