【摘要】 研究了不同冷速下交流磁场对亚共晶Al-0.90%Fe合金凝固组织的影响,试验结果表明,在交流磁场作用下,共晶组织中的Al3Fe相均向样品的中心处富集,且随着冷速降低这种趋势增大。并对交流磁场的作用机制做了探讨。更多还原

【Abstract】 The effect of an alternating magnetic field on the solidified structures of hypoeutectic Al-0.90%Fe alloy was investigated. Results showed that Al3Fe phases were accumulated at the center of specimens under the alternating magnetic field, whether solidified at 3℃/min or 0.6℃/min. Decreasing the cooling rate strengthens this tendency. The mechanism of the alternating magnetic field was discussed.更多还原
