This project seeks to determine the nucleation mechanisms operating during solidification of titanium alloys and discover potent nucleant particles that control the solidified grain size. Titanium is desirable for many applications but is difficult and expensive to manufacture into products. Understanding the nucleation process during the liquid-to-solid transformation of metals is fundamental to developing quality solidified products. The new technology seeks to lift productivity by simplifying manufacturing processes such as shape casting; improve the quality of solidified products produced by casting, welding and 3D printing; expand the application of 3D printing to a broader range of products; and reduce the cost and environmental impact of products produced by wrought processes.

该项目旨在确定在钛合金固化过程中运行的成核机制，并发现控制固化晶粒尺寸的有效核素颗粒。对于许多应用来说，钛都是可取的，但制造成产品很难且昂贵。了解金属液体到固定过程中的成核过程对于开发优质的固化产品至关重要。这项新技术试图通过简化制造过程（例如铸造）来提高生产力；提高铸造，焊接和3D打印产生的固化产品的质量；将3D打印的应用扩展到更广泛的产品；并降低由制造过程产生的产品的成本和环境影响。
