報告摘要:Abstarct:
Metal additive manufacturing enables layer-wise, digital fabrications of complex near-net-shape parts using raw metallic materials mainly in the form of powder or wire. Also, it exhibits immense promise in achieving real-time, in-process microstructural engineering and control during manufacturing of a wide variety of metals and alloys. Here, microstructural engineering refers to an engineering approach to design and build desirable microstructure and properties of a material, where porosity, grain morphology, grain boundary segregation, crystallographic texture, and phase precipitation can be engineered. In this talk, I will present recent research efforts of using microstructural engineering approaches to address the emerging concerns associated with metal additive manufacturing processes, for instance, strength and ductility trade-off, hot cracking, mechanical anisotropy, etc. This research paves the way towards high-performance additive manufacturing technology by leveraging the classical approach in materials science and engineering.
