Acquisition of a High-Temperature Controlled-Atmosphere Mechanical Testing System

这一用于先进材料实验的受控气氛机械测试系统将允许在温度高达1700摄氏度的惰性和氧化环境中进行蠕变、疲劳和准静态力学测试。研究领域包括纤维增强金属和陶瓷复合材料的高温变形，细晶陶瓷、金属和复合材料的超塑性和蠕变，金属和金属基复合材料的应力腐蚀，以及金属间化合物合金的变形缠绕。该系统将帮助建立一个复合材料研究中心，这是南加州大学的一项重大新举措。该系统还将用于与材料相关的研究项目，如牙科复合修复体的疲劳耐久性，以及先进结构材料的固体力学。

This mechanical testing system with controlled atmosphere for experiments on advanced materials will permit studies of creep, fatigue, and quasi-static mechanical testing in inert and oxidizing environments at temperatures up to 1700 Centigrade. Research areas include high-temperature deformation of fiber-reinforced metal and ceramic composites, superplasticity and creep of fine-grained ceramics, metals and composites, stress corrosion in metals and metal matrix composites, and deformation twining in intermetallic alloys. This system will help establish a center for composites research, which is a major new initiative at the University of Southern California.The system will also be used in materials-related research projects such as fatigue durability of dental composite restoratives, and solid mechanics of advanced structural materials.
