CAREER: Research and Education in Laser-Assisted Materials Processing

摘要徐9624890这部作品是在职业生涯计划下获奖的，包括研究和教育目标。该研究计划涉及激光-材料相互作用的机制和新的激光辅助材料加工技术的可能性。将开发用于确定激光诱导等离子体性质的现场诊断技术，并将探索一种“无微粒”脉冲激光沉积技术。此外，还计划对激光微细加工过程中的温度场、流体流动和熔体前沿传播进行现场诊断。用数值和实验相结合的方法来理解相变过程，将开发出一种新的“清洁”微加工工艺。该教育计划包括为本科生开发一个指导性的“激光辅助微型材料加工实验室”。此外，还将开设两门本科生/研究生课程，题为“制造业中的激光加工”和“光热无损评估”。

ABSTRACT Xu 9624890 This work was awarded under the CAREER program and includes objectives for both research and education. The research plan addresses the mechanisms of laser-material interactions and the possibilities for novel laser-assisted materials processing techniques. In-situ diagnostic techniques to determine the properties of laser-induced plasmas will be developed and a "particulate-free" pulsed laser deposition technique will be explored. In addition, in situ diagnostics for measuring the temperature field, fluid flow, and melt front propagation during laser micromachining are planned. A combined numerical and experimental approach will be applied to understanding the phase change process and a novel "clean" micromachining process will be developed. The educational plan includes the development of an instructional "Laser-Assisted Microscale Materials Processing Laboratory" for undergraduates. In addition, two undergraduate/graduate courses entitled "Laser processing in Manufacturing," and "Photothermal Non-Destructive Evaluation" will be developed.
