    Abstract

    Mechanical vibration causes problems in many applications.For this reason control of vibration energy has been an active research topic for many years.Vibration controlling efforts can be focused on different fields: excitation, transfer paths, joints, damping and sound radiation.One attractive way to solve vibration problems is to increase the damping capacity of structural materials.This paper deals with the enhanced damping capacity of Fe-Cr-X based alloys.In the present work, the effects of alloying elements and heat treatment condition on mechanical properties and internal friction were studied.Five different compositions of industrial purity raw materials were manufactured by vacuum induction melting.Hot and cold rolling of the billets were done prior to heat treatments at different temperatures (1000 °C, 1050 °C, 1100 °C, 1150 °C) and time (3 h and 6 h).Dependence of the damping capacity of the specimens on heat treatment state and excitation level were evaluated by calculating the logarithmic decrement from free decay of a cantilever beam.
