| 摘 要： | 文章研究了Cu-Al-Ni-Mn-Ti多晶形状记忆合金的相变弛豫特性。实验和理论分析表明,该合金的耗散模量和模量弛豫量的关系为M2=0.316δM,半峰宽Δlgωτ=1.735,与Debye弛豫峰对比,铜基合金热弹性马氏体相变的频率弛豫峰出现一定程度的宽化,仍属于滞弹性弛豫范畴。

| Abstract: | 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. |
