In order for mechanical engineers to make informed choices with respect to material selection they need a solid understanding of the relationships between material structures, properties, and processing. To accomplish this objective, an undergraduate Engineering Materials course has been restructured and student-conducted laboratory experiments have been added. The unique approach taken in the laboratory is first to select representative materials from each of the three basic classes of materials (metals, ceramics, and polymers), and then concurrently characterize these materials with a series of experiments which include microstructure morphology determination, microconstituent properties, bulk mechanical properties, and the effects of processing on structure and properties. By following the same set of materials through the same sequence of experiments, the students will more easily grasp the concepts of structure-property interrelationships. The result will be graduates who are more capable of making intelligent materials selection decisions for design applications. The project provides devices for examining and characterizing the materials on a microstructural scale, a uniaxial test machine, equipment for studying time-dependent deformation, and state-of-the-art data acquisition systems.

为了让机械工程师做出明智的选择 在材料选择方面， 理解物质结构之间的关系， 属性和处理。 为了实现这一目标， 本科工程材料课程已经 重组和学生进行的实验室实验， 已添加。 实验室采用的独特方法是 首先从这三种材料中选择具有代表性的材料 材料的基本类别（金属、陶瓷和聚合物）， 然后同时表征这些材料， 一系列实验，包括微观结构形态 测定，微观组份性质，整体力学 性能，以及加工对结构和 特性. 通过遵循同一组材料， 同样的实验顺序，学生会更容易 掌握结构-性质相互关系的概念。 其结果将是毕业生谁是更有能力使 智能材料选择决策 应用.该项目提供了检查和 在微观结构尺度上表征材料， 单轴试验机，研究时间依赖性的设备 变形和最先进的数据采集系统。
