DAMPING CAPACITY EVOLUTION IN MARTENSITIC-AUSTENITIC RANGE AND INFLUENCE ON SPORT APPLICATIONS

摘要

This paper present a study about internal friction (IF) properties of some metallic materials which can be used in sport applications industry (equipments, cloths, snickers). Big internal friction means big energy dissipation or big amortisation properties which influence a lot the metallic material properties and them applications. The investigation take place using a torsion pendulum and the analyze materials are different metallic compounds or alloys with big or small value of internal friction. To study internal friction of a material we have to respect the big differences of IF peaks that appear in material in austenitic martensitic range.
