| 摘 要： | 在10T强磁场下进行了Al-40％ Cu(质量分数)合金重熔凝固实验,并用金相分析方法研究了磁场对凝固组织的影响.实验结果表明,Al-40％Cu合金在10T强磁场中凝固时,析出相Al2Cu形成与磁场方向成一角度的规则排列的平面层状组织.理论分析认为:由于Al2Cu晶体在不同方向的磁化率不同,在磁场中受到磁力矩的作用而转... |

| Abstract: | Al-40%Cu Alloy was prepared under a high magnetic field.The solidification behavior of Al-40%Cu alloy was studied by optical microscope.The experimental results show that the precipitating phase Al2Cu formed alignment planar layer structure having a angle with the direction of magnetic field when Al-40%Cu alloy solidified under a high magnetic field of 10T.The theoretical analysis demonstrates that Al2Cu crystals occur a rotation under the action of the magnetic moment caused by the susceptibility differenc... |
