16MnR试样低温拉伸过程声发射特性分析

Acoustic Emission Characteristic Analysis of 16MnR During Tensile Test in Low Temperature

低温条件下,运用声发射检测方法对16MnR试样进行拉伸过程监测,采用相关性分析理论及特征参量累积分析,得出了模式识别特征以及低温环境下16MnR的声发射特性。

In low temperature, the 16MnR sample tensile test process was inspected by acoustic emission equipment. Using relativity theory and cumulative characteristic of basic parameters, the characteristic of pattern recognition and the acoustic emission characteristic of 16MnR sample in low temperature were received.
