项目摘要
Sintering is the process of forming engineering components by heating material powder under pressure. Sintering processes are widely used for the manufacturing of metallic, ceramic, and composite components for automotive, aerospace, defense, and machine tool industries. However, it is often very challenging to sinter the components free from processing-related undesirable changes in structure and properties of materials. Controlling the structure of materials during sintering becomes particularly important for highly temperature-sensitive materials such as amorphous alloys. These materials are being considered for several applications due to their outstanding mechanical and electrochemical properties. This award supports fundamental research related to the development of sintering processes for the amorphous alloys and their composites and coatings. The results of this research will lead to innovations in the strategic area of advanced manufacturing of engineering materials, identified as a key to national economic development. The research will also promote the participation of diverse groups of students in manufacturing research. In spite of their attractive properties, actual utilization of amorphous alloys in practical applications has been limited primarily due to difficulties in processing of bulk shapes using conventional solidification processing. The spark plasma sintering process involving simultaneous application of pulsed direct current and uniaxial pressure offers interesting possibilities of manufacturing bulk amorphous alloys without undesirable changes in material structure. The research team will perform experiments to investigate the fundamental mechanisms of densification for the spark plasma sintering of bulk amorphous alloys, particle reinforced and laminated composites, and thick amorphous alloy coatings. The research will elucidate the mechanisms of evolution of nanocrystalline size distribution in amorphous alloys, ductility development in composites, and tribological corrosion behavior of amorphous composite coatings. The major objective is to establish the processing-microstructure-properties correlations in these areas of research. Successful completion of this research would significantly advance the state-of-the-art in spark plasma sintering of amorphous metallic alloys leading to wider industry acceptance of the sintering technology and engineered amorphous materials in a wide range of applications.
烧结是通过在压力下加热材料粉末来形成工程组件的过程。烧结过程被广泛用于制造用于汽车,航空航天,防御和机械工业的金属,陶瓷和复合组件。但是,烧结没有与加工有关的材料结构和特性的不良变化的组件通常非常具有挑战性。在烧结过程中控制材料的结构对于高温敏感的材料(例如无定形合金)尤为重要。由于其出色的机械和电化学性能,这些材料被考虑在几种应用中考虑。该奖项支持与无定形合金及其复合材料和涂料的烧结过程开发有关的基本研究。这项研究的结果将导致工程材料高级制造的战略领域的创新,这是国家经济发展的关键。这项研究还将促进各种学生群体参与制造研究。尽管具有吸引人的特性,但在实际应用中实际利用了无定形合金的实际利用受到限制,主要是由于使用常规固化处理在处理散装形状方面的困难。火花等离子体烧结过程涉及脉冲直流和单轴压力的同时应用,提供了生产散装无定形合金的有趣可能性,而材料结构上没有不良变化。研究团队将进行实验,以研究散装非晶合金,颗粒增强和层压复合材料以及厚的无定形合金涂层的散装等离子体烧结的基本机制。这项研究将阐明无定形合金中纳米晶体大小分布的进化机制,复合材料中的延展性发展以及无定形复合涂料的摩擦学腐蚀行为。主要目的是在这些研究领域建立加工 - 微观结构 - 实验性相关性。这项研究的成功完成将大大提高无定形金属合金的火花等离子体烧结的最先进,从而在广泛的应用中更广泛地接受烧结技术和设计的无定形材料。
