Physical Modelling of Metal Forming of Bars Made of Magnesium Alloys (AZ61) / Fizyczne Modelowanie Warunków Przeróbki Plastycznej Prętów Ze Stopów Magnezu (AZ61)
Abstract
This study presents the results of physical modelling of the processes of metal forming of bars made of magnesium alloy (AZ61) obtained using two research methodologies. The study employed the Gleeble 3800 testing system for simulation of metallurgical processes and a torsion plastometer. Depending on the research methodology used, the examinations were carried out in the temperature range of 200 ÷ 400°C and strain rate of (0.1 - 10 s-1). The results obtained in the study were used to determine the value of yield stress for AZ61 alloy for different strain procedures and different temperatures and strain ratios.
