The metals industry is a vital part of the UK economy directly contributing >£10bn to the UK GDP and employing thousands of people. In particular, as the only metal produced and consumed in volume in the UK, steel is a foundation industry underpinning the UK economy. The microstructure of a steel dictates its functional and structural properties, with thermal processing being a critical factor governing the microstructure. Therefore, the ability to measure changes in microstructure at high temperature is critical to researchers in this area and important concern for steel manufacturers and component producers. Our previous collaborative work led to commercial sensors such as EMspecTM, which is used to monitor transformation in the hot strip mill, where the strip above the sensor is at temperatures up to 800 degree C, but the sensor is kept at room temperature in a water cooled jacket. In this proposal, we will make the next big step: to realise a new suite of electromagnetic instrumentation for measuring the properties of metal samples and products dynamically during thermal processing, with THE SENSORS THEMSELVES operating in the high temperature environment. This will create a suite of lab tools fitting inside furnaces that have not been available before for characterising steel at high temperatures, complementary to current dilatometry and calorimetry, which measure volumetric and thermic changes. Some important microstructural changes such as those associated with small enthalpy and/or length changes (e.g. recovery and recrystallisation events, tempering of martensitic steels) could potentially be resolved where DSC and DSD are hard to resolve. Furthermore, the instrument can potentially become a new routinely used tool in full scale metal production, e.g., on continuous annealing production lines (CAPL) or batch annealing furnaces to enhance product quality control and energy efficient operation of these processes.

金属行业是英国经济的重要组成部分，为英国 GDP 直接贡献超过 100 亿英镑，并雇用了数千人。特别是，作为英国唯一大量生产和消费的金属，钢铁是支撑英国经济的基础产业。 钢的微观结构决定了其功能和结构性能，而热处理是控制微观结构的关键因素。因此，测量高温下微观结构变化的能力对于该领域的研究人员至关重要，也是钢铁制造商和零部件生产商的重要关注点。 我们之前的合作工作催生了 EMspecTM 等商用传感器，它用于监测热带钢轧机中的转变，其中传感器上方的带钢温度高达 800 摄氏度，但传感器在水冷夹套中保持在室温。 在这个提案中，我们将迈出下一个重要的一步：实现一套新的电磁仪器，用于在热处理过程中动态测量金属样品和产品的特性，传感器本身在高温环境下运行。这将创建一套安装在炉内的实验室工具，这些工具以前没有用于在高温下表征钢，以补充当前测量体积和热变化的膨胀法和量热法。一些重要的微观结构变化，例如与小焓和/或长度变化相关的变化（例如恢复和再结晶事件、马氏体钢的回火）可能会在 DSC 和 DSD 难以解决的情况下得到解决。此外，该仪器有可能成为大规模金属生产中的一种新的常规工具，例如在连续退火生产线 (CAPL) 或批量退火炉上，以增强产品质量控制和这些过程的节能运行。
