The Materials Research Laboratory at Brown University supports major multidisciplinary research efforts that require the sustained, cooperative effort of several faculty members; central facilities that are important for much of the materials research effort on campus as well as specific MRL projects; and seed funding for promising new research efforts. The program involves 27 faculty members from Chemistry, Physics and four areas of Engineering, and also currently supports 27 graduate students and 5 postdoctoral research associates. The MRL program also involves cooperative efforts with industry and government laboratories. Research in plasticity and fracture addresses problems of fundamental importance in the mechanical behavior of a broad class of materials including metals, alloys and ceramics as well as metal-matrix and ceramic composites. The goal of the research on the microscopic basis of glass properties is an understanding of how glass structure, composition, preparation and thermal history determine glass properties and dynamics. Other research addresses the atomic mechanisms by which film growth takes place and an interface is modified. The scientists and engineers in this MRL are very well qualified to carry out the proposed research. There is a strongly interactive area of excellence in plasticity and fracture which addresses technologically important problems in an innovative way. There are adequate facilities for the proposed research. Support for the plasticity and fracture thrust will be phased out over a two-year period as support for this research from the Materials Research Groups program is phased in. Support for an orderly phase-out of the remainder of the MRL is provided for one year so that current projects can be completed.

布朗大学的材料研究实验室支持主要的多学科研究工作，这些工作需要几名教职员工的持续合作努力；对校园内的许多材料研究工作以及具体的MRL项目至关重要的中央设施；以及为有前景的新研究工作提供种子资金。该项目涉及来自化学、物理和四个工程领域的27名教职员工，目前还支持27名研究生和5名博士后研究助理。MRL计划还涉及与行业和政府实验室的合作努力。塑性和断裂的研究解决了一大类材料的力学行为中的基本问题，包括金属、合金和陶瓷以及金属基和陶瓷复合材料。研究玻璃性能的微观基础的目的是了解玻璃的结构、成分、制备和热历史如何决定玻璃的性能和动力学。其他研究涉及薄膜生长和界面修改的原子机制。这项MRL中的科学家和工程师非常有资格开展拟议的研究。在塑性和断裂领域有很强的互动性，以创新的方式解决重要的技术问题。有足够的设施进行拟议的研究。随着材料研究小组计划对这项研究的支持逐步实施，对塑性和断裂推力的支持将在两年内逐步取消。为有序地逐步淘汰最大残留限量的剩余部分提供为期一年的支助，以便能够完成目前的项目。
