从轻到强 镁领未来

记星校高中部镁材料主题展

2025年9月15日至19日，上海星河湾双语学校高中部十二年级的王思妙同学在四楼中庭策划并举办了 “中国镁助世界减负飞驰！”主题展览。本次展览以镁这一战略性新兴材料为核心，不仅聚焦了镁在轻量化、阻尼减震、电磁屏蔽等方面的独特优势，更深入展示了高通量材料基因组与人工智能计算作为材料科学前沿研究方法在镁合金研发中的应用前景。

展览从镁的晶体结构出发，延伸到镁合金的加工工艺与主要研究方向。重点突出镁的轻量化优势，现场通过钢、铝、镁哑铃的对比，让观众直观感受到密度差异；同时此次展览也展示了镁在阻尼减震、电磁屏蔽等方面的性能。展品涵盖了笔记本外壳、手机中板、汽车轮毂等日常实物，并指向新能源汽车、高铁、航空航天和智能制造等广阔应用场景。展览还特别介绍了“AI高通量计算+材料基因组”研发体系，这一前沿方法正在显著加快镁合金新材料的开发效率并降低成本，显示出极具潜力的未来价值。

值得一提的是，中国镁资源储量、产量与出口量均居世界首位，为镁产业的发展提供了坚实的战略基础。在展览现场，有老师赞叹道：“为什么会选择镁作为主题？因为它不仅轻盈，更承载着未来产业升级的可能性。”

策展人王思妙同学也分享了自己在耐腐蚀镁合金方向上的科研尝试：利用DFT（密度泛函理论）计算，调控合金中第二相元素，以抑制镁的阴极析氢反应，从而提升其耐腐蚀性。这一探索既展现了高中生的科研兴趣，也呼应了前沿科研与国家需求的紧密结合。

整场展览以“从微观到宏观，从瓶颈到突破，从实验室到生活”为主线，全面呈现了镁这一“轻量化金属之王”的科学魅力和产业价值。它不仅让参观的老师与同学们刷新了对镁的认知，更激发了大家对新材料科学的无限兴趣与想象。对策展人来说，这次展览不仅是知识的展示，更是一次勇敢尝试与自我突破；对更多同学而言，它或许也是一颗被点亮的火种，将兴趣与梦想延伸到未来的学习和人生选择之中。

From September 15th to 19th, 2025, Wang Simiao, a twelfth-grade student at Shanghai Star River Bilingual School's High School, curated and organized the themed exhibition "Chinese Magnesium Helps the World Lighten its Burden!" in the fourth-floor atrium. Focusing on magnesium, a strategic emerging material, the exhibition not only highlighted its unique advantages in lightweighting, damping and vibration reduction, and electromagnetic shielding, but also delved into the application prospects of cutting-edge materials science research methods—high-throughput materials genomics and artificial intelligence computing—in magnesium alloy research and development.

The exhibition began with the crystal structure of magnesium and extended to the processing technology and key research directions of magnesium alloys. The exhibition emphasized magnesium's lightweighting advantages, comparing steel, aluminum, and magnesium dumbbells to allow visitors to intuitively appreciate the density differences. It also showcased magnesium's performance in damping and electromagnetic shielding. Exhibits included everyday items such as laptop cases, mobile phone mid-plates, and automobile wheels, and explored a wide range of applications, including new energy vehicles, high-speed rail, aerospace, and intelligent manufacturing. The exhibition also highlighted the "AI High-Throughput Computing + Materials Genome" R&D system. This cutting-edge approach is significantly accelerating the development efficiency and reducing costs of new magnesium alloy materials, demonstrating its immense potential for future value.

Notably, China leads the world in magnesium reserves, production, and exports, providing a solid strategic foundation for the development of the magnesium industry. At the exhibition, a teacher exclaimed, "Why did you choose magnesium as the theme? Because it's not only lightweight, but also holds the potential for future industrial upgrades."

Curator Wang Simiao also shared her research on corrosion-resistant magnesium alloys: using DFT (density functional theory) calculations to manipulate the secondary phase elements in the alloy to suppress the cathodic hydrogen evolution reaction, thereby improving its corrosion resistance. This exploration not only showcases the scientific research interests of high school students but also reflects the close integration of cutting-edge research with national needs.

The exhibition, centered around the theme of "From the micro to the macro, from bottlenecks to breakthroughs, from the laboratory to everyday life," comprehensively showcases the scientific appeal and industrial value of magnesium, the "king of lightweight metals." The exhibition not only refreshed the understanding of magnesium for the visiting teachers and students, but also sparked their boundless interest and imagination in new materials science. For the curators, this exhibition was not only a display of knowledge, but also an opportunity for courageous experimentation and self-improvement. For many students, it may also be a spark that will ignite their interests and dreams, extending them to future studies and life choices.
