| 摘 要： | 采用逐层分析的方法研究了强磁场下MnBi和Al3Ni析出相的形态。发现Bi-6wt%Mn合金的铸态相中,MnBi析出相为薄片状,不呈树枝晶形貌。施加10 T磁场后,在平行磁场方向呈取向的棒状组织,在垂直磁场方向呈六方状。Al3Ni析出相在铸态组织中有初步聚合,施加10 T磁场后,沿磁场方向平行分布且层间距基本不变。

| Abstract: | The morphology of MnBi and Al3Ni in samples which solidified under 10 T high magnetic fields was studied through layer-by-layer analysis method.In the casting sample of Bi-6wt% Mn alloy,the MnBi phase was slice type but not dendrite morphology.After treated under 10 T high magnetic fields,the MnBi phase changed to a short bar shape paralleling to the field direction,and was observed as hexagon in the direction perpendicular to the field.The Al3Ni phase primary aggregated in casting sample.After treated unde... |
