摘　　要：通过差示扫描量热技术研究了不同的加热速率对CuZnAlMnNi记忆合金中双可逆相变的影响。结果表明:快速加热抑制了X→M转变却有利于马氏体逆转变,使两个相变峰靠近;随着加热速率的降低,两个相变峰逐渐分离。The influence of various heating rates on double reversible transformations in a CuZnAlMnNi shape memory alloy was investigated by differential scanning calorimetry. It is found that rapid heating inhabits the X-->M transition but is favorable to the reverse martensite transformation, giving rise to the approach of the two transformation peaks. With decrease of heating rate, the two transformation peaks are separated gradually.
