Compression Deformation Behavior of AZ81 Magnesium Alloy at Elevated Temperatures

Advances in Materials Science and Engineering, 2014
The hot deformation behavior of an AZ81 magnesium alloy was investigated by hot compressive testing on a Gleeble-1500 thermal mechanical simulator in the temperature range from 200 to 400°C and in the strain rate range of 0.001–5 s−1.

Comparison of the Mechanical Properties and Forming Behavior of Two Texture-Weakened Mg-Sheet Alloys Produced by Twin Roll Casting

Frontiers in Materials, 2019
The influence of rolling and annealing on the resulting mechanical properties and forming behavior of Mg-Zn-RE and Mg-Zn-Ca alloys produced via twin roll casting is investigated. After hot rolling followed by an annealing treatment, both alloys develop a

Magnesium and the heart: Antiarrhythmic therapy with magnesium [PDF]

Clinical Cardiology, 1993
AbstractMagnesium is an essential transmembrane and intracellular modulator of the electrical activity of cardiac cells. This review provides an up‐to‐date consideration of the cellular and clinical electrophysiological role of magnesium. This ubiquitous element seems to be important from both the theoretical and clinical point of view, because ...
