| Abstract: | Al2O3/Al composites of different volume fractions were produced by using reciprocating extrusion technology with pure Al powder and Al2O3 particle.Then the damping capacity of the composites was measured.Relationship of damping behavior and strain amplitude or frequency,and the contribution of different content of reinforced particles to damping capacity were investigated.The result shows that the Al2O3 particles homogeneously distributed in Al matrix,and the Al2O3P/Al composite prepared by reciprocating ex... |
