摘要：
The effect of static magnetic heat treatment on microstructures and mechanical properties of DZ483 alloy was investigated in combination with high temperature tensile experiments. It was found that the morphology of gamma' precipitates became spherical in the magnetic field of 12 T. Additionally, the application of magnetic field increased the tensile strength, elongation and micro-hardness of the superalloy. However, the magnetic field had no obvious effect on the reduction in area of alloys. The changes in microstructures could be attributed to the variation of the gamma/gamma' lattice misfit and interfacial energy in the magnetic field. (C) 2015 Elsevier B.V. All rights reserved.
