Acquisition of a Fatigue Crack Growth/Fracture Toughness System

这是洛杉矶洛约拉玛丽蒙特大学的仪器购置奖。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）生长速率。具体来说，疲劳裂纹扩展/断裂韧性系统是一个关键的设备，它将与其他设备结合，用于研究6xxx和7xxx系列铝合金在马弗炉中的倒退和再时效的影响。成功的结果将产生重量减轻，对铝工业有很大的好处。这是洛杉矶洛约拉玛丽蒙特大学的仪器购置奖。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）生长速率。本科学生将学习断裂力学的背景知识，以及如何使用疲劳裂纹扩展/断裂韧性系统。此外，本科生将学习到倒退和再老化的背景和本工作成功的意义。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结果结合起来，即热处理、拉伸测试和电阻率测定。

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.
