| 中文摘要: |
| 综述了 Al 合金高压凝固研究现状，着重介绍了 GPa 级高压作用下 Mg 合金凝固组织细化及细化机制研究结果，高压下 Mg 合金异质晶核结构及与 Mg 基体界面关系、异质晶核生成机制、压力对结晶相和形核衬底界面能(润湿性)的影响将成为今后 Mg 合金凝固组织细化机制研究的关键科学问题之一。介绍了与凝固组织细化相关的高压凝固理论，如非均质形核临界生核半径和临界形核功、形核率及晶体生长速率等理论模型及最新研究进展。 |
| 英文摘要: |
| The work summarizes the status quo of the research on high-pressure solidification of Al alloys and emphatically introduces the results of research on the refinement of Mg alloy solidification structure and refinement mechanism under GPa high pressure. The relationship between the structure of Mg alloy heterogeneous nuclei and Mg matrix interface, generative mechanism of heterogeneous nuclei, and the effect of pressure on crystallized phase and nucleation substrate interfacial energy (wetting property) will become one of the key scientific subjects of the research on the refinement mechanism of Mg alloy solidification structure in the future. It also introduces the theory of high-pressure solidification related to refinement of solidification structure, such as the theoretical models of critical nucleation radius of heterogeneous nucleation and critical nucleation energy, nucleation rate and rate of crystal growth, etc. as well as the latest research progress. |
