The research on internal friction and solid defects enjoys a high reputation in the world and has been active in the forefront of this field. It is the main research base in the field of internal friction in China, and has presided over and participated in previous large-scale academic conferences in this field in China. The laboratory has developed film internal friction meter, audio internal friction meter, liquid internal friction meter and multifunctional internal friction meter, and built a world-class internal friction measuring device with complete spectrum and wide temperature range. In recent years, the research field of internal friction has been expanding. Using internal friction technology, combined with other microscopic analysis methods and numerical calculation methods, the basic scientific problems such as functional ceramic materials and metal high damping materials, internal structure and phase transition process of liquids (simple metals and alloys), abnormal characteristics in polymer melts and granular materials were studied, and the internal relationship between material structure and macroscopic physical properties was revealed. The research results attracted wide attention in the world. The methods and techniques for measuring internal friction of thin films and small-scale samples are developed, and the methods and techniques for combining internal friction measurement with other physical quantities are actively explored.
