Internal Friction in Commercial Aluminium Alloy AW-2007

Popis výsledku v původním jazyce

The aim of this work is to state internal friction on stress amplitude dependence in an experimental aluminium alloy AW - 2007. Dependence was examined on sample made of extruded material after annealing at the temperatures of 200 oC and 250 oC. Annealing at the increased temperature has significant effect on dislocation structure. All slip systems are activated in material and thermally activated dislocation transport also occurs. At the same time the annihilation of dislocations with opposite direction occurs. The Frank-Read sources are removed. After quenching at the room temperature the relatively immobile dislocation forest is present in the material that does not contribute to the internal friction and does not generate new dislocations. The amplitude dependence of internal friction can be described by Granato and Lücke model, which presumes the existence of weak attached barriers in slip plane of dislocation. This model involves average dislocation length, Young's elasticity mod
