项目摘要

This is an instrument acquisition award to Loyola Marymount University in Los Angeles. A Fatigue Crack Growth/Fracture Toughness System will be purchased. The instrument will be used to study Stress-Corrosion-Crack (SCC) growth rates of various aluminum alloys. Specifically, the Fatigue Crack Growth/Fracture Toughness System is a critical piece of equipment which, in combination with other equipment, will be used to study the effect of retrogression and re-aging on 6xxx and 7xxx series aluminum alloys in muffle furnaces. Successful results will produce weight savings, a great benefit to aluminum industries.This is an instrument acquisition award to Loyola Marymount University in Los Angeles. A Fatigue Crack Growth/Fracture Toughness System will be purchased. The instrument will be used to study Stress-Corrosion-Crack (SCC) growth rates of various aluminum alloys. Undergraduate students will be taught the background of fracture mechanics and how to use the Fatigue Crack Growth/Fracture Toughness System. Additionally, the undergraduate students will learn the background of retrogression and re-aging and the significance of the success of this work. After completing the curriculum and sample experiments, the students will then incorporate the results of testing on this system with the results of other experiments, namely, heat treatments, tensile testing, and electrical resistivity determination.

这是洛杉矶洛约拉玛丽蒙特大学的仪器购置奖。将购买疲劳裂纹扩展/断裂韧性系统。该仪器将用于研究各种铝合金的应力腐蚀裂纹（SCC）增长率。具体而言，疲劳裂纹扩展/断裂韧性系统是一个关键设备，与其他设备结合使用，将用于研究退化和再时效对6xxx和7 xxx系列铝合金的影响。成功的结果将产生重量的节省，一个巨大的利益，铝工业。这是一个仪器收购奖洛约拉玛丽蒙特大学在洛杉矶。将购买疲劳裂纹扩展/断裂韧性系统。该仪器将用于研究各种铝合金的应力腐蚀裂纹（SCC）增长率。本科生将被教导断裂力学的背景，以及如何使用疲劳裂纹扩展/断裂韧性系统。此外，本科生将学习倒退和再老化的背景和这项工作的成功的意义。在完成课程和样品实验后，学生将把该系统的测试结果与其他实验的结果相结合，即热处理，拉伸测试和电阻率测定。
