The properties of phase transition relaxation of polycrystalline Cu-Al-Ni-Mn-Ti shaDe memory alloy were studied in the paper.The experiment results and theorctical analvses show that the relationship of loss modulus to modulus relaxation quantity is M_2=O.316δM and the semi-peak width is △lg ωτ=1.735 in the alloy.Compared with the Debye relaxation peak,the relaxation peak gets to some extent broadened at frequency spectra in the thermoelastic martensitic transfomation of Cubased alloy,but still belonging to a kind of anelastic relaxation.
