                      prepared by spark plasma sintering were investigated for the
                      effect of Ta content on the microstructure, mechanical and
                      damping properties. The microstructure and phase composition
                      indicate that the alloy is mainly composed of β′1
                      martensite, γ′1 martensite, Ti-rich and Ta-rich phase. As
                      the Ta content increases, the grain size of the alloy first
                      decreases and then increases. The reverse trend was observed
                      for hardness, tensile and compressive strength. The
                      hardness, tensile strength and compressive strength
                      increased by $18.2\%,$ $44.9\%$ and $28\%,$ respectively,
                      when the Ta content was 1 $wt.\%$ compared to the alloy
                      without Ta element. The presence of martensite provides the
                      alloy with promising damping properties. Meanwhile, the
                      formation of the second phase has a two-sided effect on the
                      damping characteristics. That is, the increase in grain
                      boundaries provides more interfaces for energy dissipation,
                      but the increased compressive stress between the interfaces
                      also hinders the movement of the interfaces. Excellent
                      damping performance is demonstrated with the addition of 1
                      $wt.\%$ of Ta element. The peak values of damping capacity
                      at room temperature and at about 580 °C reached 0.026 and
                      0.19, respectively. The results confirm that the addition of
                      Ta elements is achievable to obtain Cu–Al–Mn–Ti alloys
                      with both high mechanical and damping properties.},
