Passive monitoring techniques have been used for peak temperature measurements during irradiation tests by exploiting the melting point of well-characterized materials. Recent efforts to expand the capabilities of such peak temperature detection instrumentation include the development and testing of additively manufactured (AM) melt wires. In an effort to demonstrate and benchmark the performance and reliability of AM melt wires, we conducted a study to compare prototypical standard melt wires to an AM melt wire capsule, composed of printed aluminum, zinc, and tin melt wires. The lowest melting-point material used was Sn, with a melting point of approximately 230 °C, Zn melts at approximately 420 °C, and the high melting-point material was aluminum, with an approximate melting point of 660 °C. Through differential scanning calorimetry and furnace testing we show that the performance of our AM melt wire capsule was consistent with that of the standard melt-wire capsule, highlighting a path towards miniaturized peak-temperature sensors for in-pile sensor applications.
被动监测技术已被用于辐照试验中的峰值温度测量,方法是利用经过良好表征的材料的熔点。最近,人们努力扩展这种峰值温度检测仪器的功能,包括开发和测试增材制造(AM)的熔体丝。为了展示和基准化 AM 熔体丝的性能和可靠性,我们进行了一项研究,将原型标准熔体丝与由打印的铝、锌和锡熔体丝组成的 AM 熔体丝胶囊进行了比较。使用的最低熔点材料是 Sn,熔点约为 230°C,Zn 的熔点约为 420°C,而高熔点材料是铝,熔点约为 660°C。通过差示扫描量热法和炉内测试,我们表明我们的 AM 熔体丝胶囊的性能与标准熔体丝胶囊一致,为堆内传感器应用的小型化峰值温度传感器开辟了道路。
