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.

这一机械测试系统具有受控气氛，用于先进材料的实验，可在惰性和氧化环境中进行蠕变、疲劳和准静态机械测试研究，温度可达1700摄氏度。 研究领域包括纤维增强金属和陶瓷复合材料的高温变形，细晶粒陶瓷、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，以及金属间合金的变形孪晶。 该系统将有助于建立复合材料研究中心，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，如牙科复合材料的疲劳耐久性，以及先进结构材料的固体力学。
