中文摘要：

将Cu-15％Fe（质量分数）合金在强磁场中进行不同固溶时效处理，研究了合金的时效行为．结果表明，箍加10T强磁场可以促进第二相Fe枝晶的球化，而且Fe枝晶的形貌受强磁场的球化作用与高温缓慢冷却引起的粗化作用的影响．在Cu-15％Fe合金1000℃固溶处理中，施加10T强磁场使基体中的Fe含量降低了0．39％．这表明，强磁场在一定程度上促进了Fe在Cu基体中的析出，获得与缓冷相类似的效果；施加10T强磁场固溶处理并在10T强磁场作用下经500℃时效处理后，基体中的Fe含量较低．其原因是，旖加强磁场后Fe原子的析出规律受温度制度和析出相磁性转变的共同影响．施加强磁场改变了原子的激活能，进而影响了原子的扩散行为．

英文摘要：

The investigations on the solution and aging treatment of Cu-15%Fe （mass fraction） alloy imposed by a high magnetic field show that, high magnetic field can promote spheroidization of the Fe dendrites in Cu matrix, and the spheroidization and coarsening caused by slow cooling at high temperature determine the morphology of Fe dendrites. High magnetic field can promote the precipitation of Fe in Cu matrix, which is similar to the effect of slow cooling. Further, the solubility of Fe in Cu matrix is minimum as the aging temperature is 500℃ under 10 T high magnetic field, which is because of the combined action of temperature profile and magnetic transformation of precipitations when imposed by high magnetic field. The theoretical analysis shows that the activation energy of atoms is changed by imposition of high magnetic field, and therefore affects the diffusion behavior of atoms.
