综述了非磁性金属在再结晶和晶粒长大过程中磁场影响织构和组织演变的最新研究进展。磁退火可以有效地影响锌、钛和锆磁各向异性晶体生长过程中的显微组织发展。这是由于晶界运动的额外驱动力，这是由于不同取向的颗粒之间的磁性自由能密度的差异引起的。在磁场作用下，各向异性非磁性材料中的晶粒生长动力学发生了很大的变化。然而，磁场不仅会影响组织的长大阶段，而且还会影响组织的早期阶段，即回复和初次再结晶。此外，磁场的影响并不局限于磁各向异性金属，而是可以在具有磁各向同性属性的材料中观察到。
The latest research on magnetically affected texture and grain structure evolution during recrystallization and grain growth in non-magnetic metals is reviewed. The microstructure development during grain growth in magnetically anisotropic zinc, titanium and zirconium can be effectively influenced by means of magnetic annealing. This is due to an additional driving force for grain boundary motion which arises from a difference in magnetic free energy density between differently oriented grains. Grain growth kinetics in anisotropic non-magnetic materials is substantially modified in the presence of a magnetic field. However, a magnetic field can affect the microstructure evolution not only at the stage of grain growth, but also at earlier stages, i.e. recovery and primary re-crystallization. Also, the impact of a magnetic field is not confined to magnetically anisotropic metals but can be observed in materials with magnetically isotropic properties.
