随着加热技术(加热炉设计和电子程序控制)和位移控制器的发展,膨胀仪的应用范围在不断扩大,满足了人们为改进金属材料的使用性能,更深入地了解和控制高速、非恒温热处理时材料结构变化的要求。近来,与快速,甚至反复加热相关的现象受到进一步重视,这就不仅促进了膨胀仪的不断完善,同时也促进了新型膨胀仪的设计,以满足科 With the development of heating technology (furnace design and electronic program control) and displacement controllers, dilatometer applications have been expanded to meet people’s need to improve the performance of metal materials, to better understand and control high-speed, non-constant temperature Requirements of material structure change during heat treatment. Recently, more attention has been paid to the phenomena related to rapid and even repeated heating. This has not only contributed to the continuous improvement of dilatometers, but also promoted the design of new dilatometers to meet the needs of families
