摘要：
The effect of magnetic field on precipitation phases in directional solidified single-crystal nickel-base superalloy was investigated. The magnetic field significantly decreases the size of gamma' and the content of carbides and gamma/gamma' eutectic. The decreased magnitude is firstly sharp and then gentle with the increasing magnetic field intensity. The gamma' phase refinement could be attributed to a decrease in nucleation activation energy during solid phase transformation. The segregation reduction of alloying elements is responsible for the content decrease of carbides and gamma/gamma' eutectic. The magnetic-field-assisted directional solidification provides an effective way to control the size and content of precipitation in superalloys. (C) 2013 Elsevier B.V. All rights reserved.
