This new approach is applied to a magnesium alloy AZ61. Torsion tests were carried out in the temperature range 574–734 K and strain rate range 0.7–8.7 s and the microstructures were determined using optical microscopy. Using the peak stress, optimum
Magnesium (Mg) and its alloys can degrade gradually up to complete dissolution in the physiological environment. This property makes these biomaterials appealing for different biomedical appliions, such as bone implants. In order to qualify Mg and its alloys for bone implant appliions, there is a need to precisely model their degradation (corrosion) behavior in the physiological
