【Abstract】 The directive studies and its extend progress in both the spectra and mechanism of the internal friction in iron-based materials,which were completed and obtained by the authors and cooperators,are introduced.The discussion on the mechanism of the damping phenomena of deformation enhanced Snoek effect(DESE),B-deformation peak,Snoek-Kê-Kster(SKK)peak,and Kêpeak and so on has been made.A discussion to several basic and contentious problems is also made.更多还原
