Analysis of dependence of internal damping on temperature of austenitic steels AISI 304 and AISI 316L

The article is focused on the analysis of dependence of internal damping on temperature of austenitic steels. The ability of a solid to irreversibly disperse energy under mechanical stress is called the internal damping. The time required to achieve the equilibrium deformation value is determined by various processes associated with the reallocation of atoms, magnetic moments and the temperature of the solid subjected to external stresses. Measurement of internal damping dependence on temperature was performed on austenitic steels AISI 304 and AISI 316L, in the initial state and after the deformation. Those materials are the most important group of corrosion-resistant metallic materials, which are very often used in industrial. Significant future growth is foreseen in the use of stainless steel for key structural components in automotive construction. Due to its unique mechanical properties, stainless steel can add an extra dimension of passenger safety, especially in the way that a large part of the energy produced in a collision is absorbed as the material deforms under impact. This property is already put to good effect in the design of modern large passenger vehicles such as buses, but the future potential in all types of road vehicle is immense (www.worldstainless.org).
