Influence of composition and heat-treatment on damping capacity of Cu-Al alloys
The compositions,structures and properties of four kinds of Cu-Al alloys with different constituents were researched by means of optical microscopy,scanning electron microscopy,X-ray diffractometry and damping detection.The structures and properties of Cu-11Al-5Mn-RE experienced different heat-treatment processes were also studied.The results indicate that the damping capacity and microstructure of the alloys are improved by adding Mn and RE elements.Cu-11Al-5Mn-RE obtains the best comprehensive physical performance because of the cooperation of Mn and RE elements.Aging at 200 ,℃ the damping capacity gets to the maximum.At 400 ,its mechanical property decreases while its damping capacity still remain ℃ s,indicating its resistance to martensite decomposition and aging at moderate temperature.
