Acquistion of Instrumentation for Materials Characterization and Nondestructive Evaluation

#0619232材料表征和无损评估仪器的获得该奖项资助的仪器填补了巴克内尔大学正在开发的材料表征和无损评估(NDE)设施中的一个重要空白。该设施为机械工程、土木工程和环境工程以及化学工程部门提供表征和无损检测能力。选择了特定的设备和配套仪器，以便为研究用户提供当前和计划在以下领域开展的项目的最大益处：(A)分析纳米材料和硬质涂层中的应力腐蚀破裂和腐蚀疲劳机理的基础研究；(B)新材料系统中的微结构和性能关系；以及(C)材料的工艺变化和表征。该设备包括一个带有过滤和数据可视化软件的声发射(AE)系统，以及一个带有Z-Scan双轴扫描仪的超声波测试(UT)系统，这两个系统都对正在进行的研究的成功至关重要。选择台式机和手持机型是为了提供必要的灵活性和便携性。该设备是对最近为开发设备购买的扫描电子显微镜(SEM)、倒置光学显微镜、X射线荧光(XRF)光谱仪和恒电位仪/恒电流计的补充。不同院系的多个教员使用这种设备，进一步增强了相关研究的跨学科性质。收购的更广泛影响包括加强材料表征和无损评估的设施。改善的设施预计也将对目前和未来为初中生和高中生提供的外展计划以及为与该学院小企业发展中心合作的当地企业提供的服务产生重大影响。开发中的实验室使本科生研究活动更好地融入相关课程的教学，并增加了让行业合作伙伴参与本科生和硕士水平研究项目的前景。通过在不同课程中开展类似活动培养学生的意识，私人投资促进师相信，新的无损检测设施将进一步提高人们对材料研究和开发的兴趣。将向更广泛的材料教育、研究和社区传播研究成果以及与该工具一起开发的新课程材料和教学方法。

#0619232Acquisition of Instrumentation for Materials Characterization and Nondestructive Evaluation The instrumentation funded by this award fills a crucial void in a developing Materials Characterization and Nondestructive Evaluation (NDE) facility at Bucknell University. The facility supplies characterization and NDE capabilities to the departments of Mechanical Engineering, Civil and Environmental Engineering, and Chemical Engineering. The specific equipment and accompanying instruments have been selected to provide the maximum benefit to research users with current and planned projects in the areas of: (a) fundamental studies in the analysis of stress corrosion cracking and corrosion fatigue mechanisms in nanomaterials and hard coatings (b) microstructure and property relationships in novel material systems and (c) process variation and characterization of materials. The equipment includes an acoustic emission (AE) system with filtering and data visualization software, and an ultrasonic test (UT) system with Z-scan dual axis scanner, both critical to the success of ongoing research. Desktop and handheld models were selected to provide necessary flexibility and portability. This equipment complements the scanning electron microscope (SEM), inverted optical microscope, X-ray fluorescence (XRF) spectrometer, and potentiostat/galvanostat recently acquired for the developing facility. The use of this equipment by multiple faculty in different departments further enhances the multidisciplinary nature of related research. The broader impacts of the acquisitions include the enhancement of facilities for materials characterization and nondestructive evaluation. Improved facilities are also expected to have a significant impact on current and future outreach programs offered to middle and high school students, as well as services available to local businesses working with the college's Small Business Development Center. The developing laboratory allows for improved integration of undergraduate research activities into the teaching of related courses, and enhanced prospects for involving industry partners in undergraduate and masters-level research projects. Through student awareness developed with similar activities in a variety of courses, the PIs believe that the new NDE facilities will further increase interest in materials research and development. Research results, and new curricular materials and pedagogical approaches developed with the instrumentation, will be disseminated to the broader materials education and research and community.
