摘要:

近年來，利用強磁場的洛倫茲力、磁化力、磁化能和磁極化交互作用等效應開展材料可控制備，獲得新的組織結構和性能，已成為材料研究領域的熱點問題之一。強磁場不僅可以從宏觀上控制材料的物理、化學反應過程，還能影響和調節物質內部的微觀狀態。同時，強磁場對制備產物的生長過程、最終形貌、排列方式和組織結構等均有重要影響。主要介紹了強磁場在控制化學反應過程、薄膜材料制備、金屬凝固過程等方面應用的研究現狀，從吉布斯自由能、反應平衡系數、磁化率各向異性、磁疇結構、溶質擴散等角度解釋了磁場改變材料組織結構、性能等現象的產生原因，討論了外加磁場在材料科學領域應用中的研究現狀、存在的問題及發展前景。

Abstract:

In recent years, applying Lorentz force, magnetization force, magnetization energy and magnetic polarization interaction of high magnetic fields to obtain new microstructures and properties has become one of hot spots of materials research. The high magnetic field can not only control the physical and chemical reaction process of materials in the macro level, but also affect and regulate the microstructures of materials. The high magnetic field has an important influence on the growth process and the final morphology, microstructure arrangement and phase structure of the prepared products. The research status of high magnetic field on controlling chemical reaction process, preparation of film materials and metal solidification process was mainly introduced. Furthermore, the changes of microstructure and properties were explained from the perspectives of Gibbs free energy, equilibrium coefficient, magnetic susceptibility anisotropy, magnetic domain structure, solute diffusion, and etc. Finally, the research situation, problems and prospects of applying magnetic fields in materials science were discussed in detail.
