Abstract Scope |
Phase transformation and resultant phase structure are essential for engineered property and performance of additively manufactured metallic components. However, rapid solidification occurring in laser additive manufacturing typically renders phase transformation far from equilibrium and inevitably challenges the prediction of complex phase structure and selection of favored phases. Here, we report phase transformation dynamics of melt pool revealed by synchrotron in-situ experiments and ab initio molecular dynamics simulation. The physics of atomic structure transition and consequent processing-structure-property relationship will be discussed. The discovery of phase transformation dynamics deepens fundamental understanding of phase structure control in the rapid solidification process of laser assisted manufacturing and formulates novel insights for alloy design of metal 3D printing. |
