U.S.-Korea Cooperative Science: High-Strength and Wear-Resistant Nanocomposite Al-Base Alloys by Rapid Solidification Processing

该奖项支持科罗拉多矿业学院的Challapalli Suryanarayana博士和韩国忠咸国立大学的B. S. Chun教授之间为期3年的合作研究项目。本研究旨在通过快速凝固工艺开发高强度、耐磨的纳米复合al基合金。Al-Si合金传统上用于工业耐磨目的，因为Si相的高体积分数赋予Si相良好的耐磨性，这可以通过快速凝固处理（RSP）技术实现。该项目将在韩美合作科学项目下，与忠咸大学千教授研究组一起进行。忠南大学的快速凝固设备非常先进，将对含有Fe、Cr、Zr、Ni等过渡金属的多种al - si基合金进行快速凝固处理（RSP）。主要含有Si和过渡金属的铝合金将受到RSP，其显微组织和机械性能将被评估。还将尝试在工业环境中测试这些合金。该项目与美韩合作科学项目（U.S.- korea Cooperative Science Program）的目标相关，该项目旨在通过科学信息、思想、技能和技术的交流以及在互利问题上的合作，提高美韩科学家和工程师之间的合作水平。韩国的参与得到了韩国科学工程财团（KOSEF）的支持。

9910531Suryanarayana This award supports a 3-year collaborative research project between Dr. Challapalli Suryanarayana, Colorado School of Mines, and Professor B. S. Chun, Chungham National University, Korea. The proposed research aims to develop high-strength and wear-resistant nanocomposite Al-base alloys by rapid solidification processing. Al-Si alloys have been traditionally used in the industries for wear resistance purposes because the high volume fraction of the Si phase imparts good wear resistance of the Si phase, and this can be achieved by rapid solidification processing (RSP) techniques. This project will be performed in conjunction with Professor Chun's group at Chungham National University, Korea under the U.S.-Korea Cooperative Science Program. Excellent facilities exist for rapid solidification at the Chungnam National University in Taejon, Korea where rapid solidification processing (RSP) of Al-Si-base alloys will be conducted on a variety of Al-Si-based alloys containing transition metals like Fe, Cr, Zr, and Ni. Aluminum alloys containing essentially Si and transition metals will be subjected to RSP and their microstructural and mechanical properties will be evaluated. Attempts will also be made to test these alloys in an industrial environment.This project is relevant to the objectives of the U.S.-Korea Cooperative Science Program, which seeks to increase the level of cooperation between U.S. and Korean scientists and engineers through the exchange of scientific information, ideas, skills, and techniques and through collaboration on problems of mutual benefit. Korean participation is supported by the Korea Science and Engineering Foundation (KOSEF).
