Abstract Accurate temperature measurement remains a challenge for microwave heating of powder materials. We propose a temperature calibration method based on exothermic reactions and the resultant thermal runaway that occurs during microwave heating. The approach was demonstrated on microwave heating of four titanium alloys. Differential scanning calorimetry was used to determine the threshold reaction temperature for each selected titanium alloy. This served as a standard for the microwave heating of these titanium alloys. Infrared pyrometric temperature measurements were then calibrated by comparing the starting temperature of each thermal runaway event with the threshold reaction temperature.

在粉末材料的微波加热中通过红外高温计校准温度测量：基于放热反应的方法

摘要 精确的温度测量仍然是粉末材料微波加热面临的挑战。我们提出了一种基于放热反应和微波加热过程中产生的热失控的温度校准方法。该方法在四种钛合金的微波加热上进行了演示。差示扫描量热法用于确定每种选定钛合金的阈值反应温度。这作为这些钛合金微波加热的标准。然后通过比较每个热失控事件的起始温度与阈值反应温度来校准红外高温温度测量值。
