Date: 2019/10/28 Author: WU Xuebang

Professor Leszek B. Magalas from AGH University of Science and Technology, Poland, was invited to visit Institute of Solid States of Physics (ISSP), CAS, from October 8 to 13. Prof. Magalas visited the Laboratory of Internal Friction and Defects in Solids Laboratory, and made in-depth discussions and exchanges with the researchers on the application of internal friction and mechanical spectroscopy, how to improve the measurement accuracy, and the analysis and processing of internal friction data. The technical details of the joint development of high-resolution internal friction apparatus were also discussed.

On October 11, Professor Magalas gave a report entitled "High-resolution mechanical spectroscopy, HRMS: progress, challenges and perspectives". In his talk, Magalas first introduced the origins of international internal friction and mechanical spectroscopy and the contributions of Professor Zener to internal friction and related fields. Subsequently, he focused on several methods for measuring internal friction and modulus, such as constant stress strain relaxation, free decay and forced vibration, and how to eliminate the main factor affecting the measurement accuracy of the internal friction apparatus such as zero-point drift and noise. Through years of hard work, He has developed some methods and software packages to solve the problem of zero-point drift and noise impact on internal friction data, which can be used for standardization and calibration of various internal friction apparatus. After the report, the participants had an in-depth discussion with Magalas on the report and their research work.

Professor Magalas focuses on anelasticity, internal friction and damping materials. He has published more than 50 papers in academic journals and presented more than 70 invited reports. He is a member of the International Conference on Internal Friction and Mechanical Spectroscopy. In 2017, he was awarded the Zener Medal, the highest award in the internal friction and mechanical spectroscopy community.
