纵向磁场对不同尺寸定向凝固高温合金DZ417G组织的影响
DOI: 10.3724/SP.J.1037.2011.00621, PP. 629-635
Keywords: 镍基高温合金,磁场,定向凝固,枝晶,热电磁对流
Abstract:
进行了外加纵向静磁场下高温合金DZ417G的定向凝固实验,考察了纵向磁场对不同尺寸试样凝固组织形貌的影响.结果显示,在温度梯度为70℃/cm,抽拉速率为5μm/s时,施加磁场后一次枝晶间距减小,并在试样边缘出现等轴晶组织;随着试样尺寸的增大,在试样边缘和中心的柱状枝晶组织遭到破坏,形成等轴晶组织,且出现“斑状”偏析.这些现象可归结为磁场在固/液界面前沿合金熔体中诱发的热电磁对流(TEMC)所致.
