项目摘要

A scientific framework will be established for field processing of nanosize particulate materials. In particular, a detailed theoretical-experimental program will be pursued with specific goals to: (a) evaluate and clarify the interdependence of material properties, geometry of microstructure and processing parameters of nanosize powders, (b) quantify the conduction of electric current through sintering nanopowder compacts and relate them to manufacturing and properties, and (c) develop a process design/characterization methodology for this technology that is applicable to nanocrystalline materials for large and net shape parts.This project will: (a) generate fundamental knowledge of the role of size scale in field processing, (b) elucidate specific mechanisms responsible for the enhanced performance of field sintering, (c) provide a rational basis for process design and optimization of this process, (d) provide guidance for the development of new models for design of complex shape processing in terms of optimization of current application, as well as die design. In addition, we will generate sizable specimens of nanocrystalline materials that will be extensively characterized for structure, defects and mechanical properties.Structural materials with grain size less than 100 nm are characterized by unusually high strength, hardness and wear resistance, as well as good fatigue resistance. This project focuses on the manufacturing and characterization of bulk nanocrystalline materials produced by field assisted sintering that can produce near net-shape bulk components starting from nanosize powders, and retains the scale of the microstructure during processing. The development of a scientific processing base for manufacturing of bulk nanoscale materials will be a major step towards commercialization of this exciting new class of materials which preserve nanometric grain size and combine unusual properties. This collaborative proposal between two Universities will provide a synergistic effect to enhance both modeling performed at Drexel University and nano-process understanding by experiments at University of California Davis.The integration of education and training within the research program will be achieved by developing a seminar course for Drexel and UCD students on "Manufacturing of bulk nanomaterials". We will continue involving undergraduate students in research by REU supplements.
建立纳米颗粒材料现场加工的科学框架。具体而言,详细的理论-实验方案将与具体目标进行:(a)评估和澄清材料特性、微观结构几何形状和纳米级粉末的加工参数之间的相互关系;(b)量化烧结纳米粉末压块的电流传导,并将其与制造和性能联系起来;(c)为该技术开发一种工艺设计/表征方法,该方法适用于用于大型和净形状部件的纳米晶体材料。该项目将:(a)产生关于尺寸尺度在现场加工中的作用的基本知识,(b)阐明提高现场烧结性能的具体机制,(c)为该工艺的工艺设计和优化提供合理的基础,(d)为复杂形状加工设计的新模型的开发提供指导,优化当前应用,以及模具设计。此外,我们将生成相当大的纳米晶体材料样品,这些样品将广泛地表征其结构,缺陷和机械性能。粒径小于100 nm的结构材料具有极高的强度、硬度和耐磨性,并具有良好的抗疲劳性能。本项目侧重于通过场辅助烧结生产块状纳米晶材料的制造和表征,该材料可以从纳米级粉末开始生产接近净形状的块状部件,并在加工过程中保持微观结构的规模。开发用于制造大块纳米级材料的科学加工基地将是这种令人兴奋的新型材料商业化的重要一步,这种材料既保留了纳米粒度,又具有不同寻常的性能。这两所大学之间的合作提议将提供协同效应,以加强德雷克塞尔大学的建模和加州大学戴维斯分校的纳米工艺实验的理解。通过为德雷克塞尔大学和都柏林大学的学生开设“块状纳米材料制造”的研讨会课程,将教育和培训整合到研究项目中。我们将继续让本科生参与REU补充研究。
