A comparative analysis of the magnetic, size and deformation effects of martensitic transformation in aged Cu–Al–Mn alloys with a minimum width of the temperature hysteresis was performed. According to the experimental studies of the behavior of alloys during martensitic transformations, the changes in temperature dependences of thermal expansion, magnetic susceptibility and electrical resistance, depending on preliminary thermomagnetic treatment of alloys, were found. The thermomagnetic treatment contributes to a change in the magnitude of volume effect of martensitic transformation. Using magnetic analysis, the state and distribution of precipitated particles, affecting both the magnetic characteristics and the volume effects of martensitic transformation in the alloys, were determined.

对具有最小温度滞后宽度的时效Cu–Al–Mn合金中马氏体相变的磁性，尺寸和变形效应进行了比较分析。根据对马氏体相变过程中合金行为的实验研究，发现了取决于合金的初步热磁处理的热膨胀，磁化率和电阻随温度的变化。热磁处理有助于改变马氏体相变的体积效应的大小。使用磁性分析，确定了影响合金的磁性和马氏体相变的体积效应的沉淀颗粒的状态和分布。
