This a two-year collaborative research project between Dr. Angus Hellawell, Michigan Technological University and Professor Lu Shu-Zu, University of Science and Technology in Beijing. This proposal plans to examine the microstructures and mechanical properties of aluminum base alloys using a series of metallic elements. It addresses an important problem in metallurgy and is a valuable line of inquiry which to date has seen little research effort. This study can make significant contributions to the understanding of structures and mechanical properties of rare earth alloys. The supply of rare earth alloys for this research is to be provided by the Chinese P.I., since eighty percent of world deposits of these rare alloys are located in China. This research can significantly advance our under- standing of the whole class of A1-Si alloys, which are currently widely used in automotive engines in the U.S.

这是密歇根理工大学的Angus Hellawell博士和北京科技大学的Lu Shu-Zu教授为期两年的合作研究项目。本课题计划利用一系列金属元素对铝基合金的显微组织和力学性能进行研究。它解决了冶金学中的一个重要问题，是一个有价值的研究方向，迄今为止研究工作很少。该研究对了解稀土合金的结构和力学性能具有重要意义。由于世界上80%的稀土合金矿藏位于中国，因此本研究所需的稀土合金供应将由中国石油工业研究院提供。这一研究可以大大提高我们对目前广泛应用于美国汽车发动机的A1-Si合金的认识
