Acoustic Emission Signals Characteristics of Q345R at Tensile Progress in the Normal and Low Temperatures

Abstract:

Acoustic emission signals were collected during the tensile process of Q345R at the normal and low temperatures. The signals were analyzed by the single parameter analysis, distribution analysis and correlation analysis to result the acoustic emission characteristics of Q345R in the normal and low temperatures.
