Investigation of mechanical properties and microstructure development of AZ61 alloy during rolling, forging and ECAP

Popis výsledku v původním jazyce

Results of experiments, focused on development of modified AZ61 alloy structure after hot forming, are summarized in this paper. Microstructure changes of the alloy after rolling and forging at temperatures of 380°C and after ECAP processed at 250°C wereobserved. After forging, the original grain size was reduced almost 14 times down to a value around 9 ?m. After ECAP the grain size reduction was even better, almost 60 times. Important role of the ß-phase (Mg17Al12) in this alloy, during plastic forming, was confirmed. Independently of processing technology, the best final properties of the AZ61 alloy were supported with very fine particles distributed in the Mg matrix. The experiment succeeded in proving the influence of precipitates on restoration processes too.
