借助于自制的“柔性”波导杆及自制的自动控温加热炉，完成了常见容器用钢１６ＭｎＲ材料试样在高温条件下声发射特性的试验研究。同时，对同样的试样还进行了常温条件下的试验，以便与高温时结果相比较。试验结果表明，随着温度的升高，材料的声发射活动性减弱，但若材料上存在缺陷，高温时仍可以监测其开裂和扩展过度，而且带切口试样在高温拉伸过程中出现两次断裂，相应产生的声发射也相当丰富。同时也表明，波导杆的合理设计和使用对研究材料高温下的声发射特性及高温设备、结构的监测有重要作用。
With the help of self-made “flexible” waveguide rod and self-made self-heating furnace, the experimental study on the acoustic emission characteristics of the common 16MnR steel container samples under high temperature conditions was completed. At the same time, the same sample was also tested at room temperature to compare with the result at high temperature. The experimental results show that as the temperature increases, the acoustic emission activity of the material decreases. However, if the material has defects, it can still be monitored for cracking and over-expansion at high temperature. In addition, Sub-fracture, the corresponding acoustic emission is also very rich. At the same time, it also shows that the rational design and use of waveguide rods plays an important role in studying the acoustic emission characteristics at high temperature and the monitoring of high temperature equipment and structures.
