摘要:

近年來(lái)，利用強(qiáng)磁場(chǎng)的洛倫茲力、磁化力、磁化能和磁極化交互作用等效應(yīng)開(kāi)展材料可控制備，獲得新的組織結(jié)構(gòu)和性能，已成為材料研究領(lǐng)域的熱點(diǎn)問(wèn)題之一。強(qiáng)磁場(chǎng)不僅可以從宏觀上控制材料的物理、化學(xué)反應(yīng)過(guò)程，還能影響和調(diào)節(jié)物質(zhì)內(nèi)部的微觀狀態(tài)。同時(shí)，強(qiáng)磁場(chǎng)對(duì)制備產(chǎn)物的生長(zhǎng)過(guò)程、最終形貌、排列方式和組織結(jié)構(gòu)等均有重要影響。主要介紹了強(qiáng)磁場(chǎng)在控制化學(xué)反應(yīng)過(guò)程、薄膜材料制備、金屬凝固過(guò)程等方面應(yīng)用的研究現(xiàn)狀，從吉布斯自由能、反應(yīng)平衡系數(shù)、磁化率各向異性、磁疇結(jié)構(gòu)、溶質(zhì)擴(kuò)散等角度解釋了磁場(chǎng)改變材料組織結(jié)構(gòu)、性能等現(xiàn)象的產(chǎn)生原因，討論了外加磁場(chǎng)在材料科學(xué)領(lǐng)域應(yīng)用中的研究現(xiàn)狀、存在的問(wèn)題及發(fā)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.
