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.

该项目旨在确定钛合金凝固过程中的成核机制，并发现控制凝固晶粒尺寸的有效成核剂颗粒。钛对于许多应用都是理想的，但制造成产品困难且昂贵。了解金属从液态到固态转变过程中的成核过程是开发优质固化产品的基础。新技术旨在通过简化形状铸造等制造工艺来提高生产率；提高铸造、焊接和3D打印生产的凝固产品的质量；将3D打印的应用扩展到更广泛的产品领域；降低锻造工艺生产的产品的成本和对环境的影响。
