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).

9910531 Suryanarayana该奖项支持一个为期3年的合作研究项目之间的博士Challapalli Suryanarayana，矿业的科罗拉多学校，和教授B。S. Chun，Chungham National University，Korea. 本研究旨在利用快速凝固技术制备高强度、高耐磨性的纳米复合铝基合金。 Al-Si合金传统上用于工业中的耐磨性目的，因为Si相的高体积分数赋予Si相良好的耐磨性，并且这可以通过快速凝固处理（RSP）技术来实现。 该项目将与韩国忠汉国立大学的Chun教授的小组一起在美国-韩国合作科学计划。 在韩国泰全的忠南国立大学，存在用于快速凝固的优良设施，其中将对含有过渡金属如Fe、Cr、Zr和Ni的各种Al-Si基合金进行Al-Si基合金的快速凝固处理（RSP）。 主要含有Si和过渡金属的铝合金将经受RSP，并将评估其微观组织和机械性能。 还将尝试在工业环境中测试这些合金。该项目与美国的目标有关。韩国合作科学计划，旨在通过科学信息、思想、技能和技术的交流，以及通过在互利问题上的合作，提高美国和韩国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与工程基金会（KOSEF）的支持。
