A thermal analysis instrument for research on materials processing is to be acquired for studies on the fabrication of powder structures into net-shaped components. The device is designed for the observation of volatile processing-aid burnout during heating to the sintering temperature. It will be applied to injection molded and die compacted structures, where lubricants, contaminants, moisture, or other volatile species are present on the powder surface. Proper thermal cycle design requires knowledge on the type, amount, and temperature where the volatile species exit the compact, allowing thermal cycle definition in both research and production equipment. The instrumentation will allow examination of actual components in realistic processing atmospheres, with simultaneous analysis of the heat flow, chemical reactions, and decomposition species. It will be most useful in the design of efficient cycles and effective polymers for powder processing, with improved properties and dimensional tolerances in sintered devices. This equipment award will provide researchers in materials processing and characterization the opportunity to determine optimized conditions for the manufacturing of sintered products.

将购置一台用于材料加工研究的热分析仪器，用于研究将粉末结构制成净形部件。 该装置设计用于观察加热至烧结温度期间挥发性加工助剂的燃尽情况。 它将应用于注塑成型和模具压实结构，其中润滑剂，污染物，水分或其他挥发性物质存在于粉末表面。 正确的热循环设计需要了解挥发性物质离开压块的类型、数量和温度，从而在研究和生产设备中定义热循环。 该仪器将允许在真实的处理气氛中检查实际组件，同时分析热流、化学反应和分解物质。 这将是最有用的设计有效的周期和有效的聚合物粉末加工，改善性能和尺寸公差的烧结设备。 该设备奖将为材料加工和表征领域的研究人员提供确定烧结产品制造的最佳条件的机会。
