RIA: Processing and Properties of Nanocrystalline Metals and Alloys

本研究计划是合成和加工宏观、致密、纳米相金属和合金，以系统研究非平衡材料的基本性质。重点将给予他们的致密化和变形行为和机制，以及他们的微观结构演化动力学和热力学稳定性。将努力获得大样本，以便进行传统的机械测试。固结过程中的超高压将用于增强致密化过程中的塑性变形，以获得小晶粒尺寸和减少晶粒生长机会的优点。＊＊＊

9409750 Ma This Research Initiation Proposal is to synthesize and process macroscopic, dense, nanophase metals and alloys for a systematic study of the fundamental properties of non-equilibrium materials. Emphasis will be given to their densification and deformation behaviors and mechanisms, as well as their kinetics of microstructural evolution and thermodynamic stability. Efforts will be directed towards obtaining large samples which will then allow traditional mechanical tests to be conducted. Extraordinarily high pressures during consolidation will be used to enhance plastic deformation during densification in order to obtain the advantages of small grain size with reduced chances of grain growth. ***
