The deformation and failure behavior of an AM60 magnesium alloy was investigated using tensile test on circumferentially notched specimens with different notch radii. The strain and stress triaxiality corresponding to the failure point were evaluated using both analytical and finite element analyses. Combining with systematical observations of the fracture surfaces, it is concluded that deforma...

Friction stir welding is used as a solid state joining process for soft materials such as aluminium alloys and also for hard materials like steels. It avoids many of the common problems obtained in fusion welding. In mechanical, civil, automobile, naval, and aeronautical engineering beams are widely used of the magnesium alloys for different applications and that are joined by conventional iner...

Annually several million people suffer bone fractures caused by accidents or diseases. Many of those fractures are too complex for an external medical treatment but have to be surgically fixated by internal bone implants. Traditional methods of osteosynthesis or osteotomy use permanent metal implants e.g. bone screws and bone plates made of steel or titanium alloys, but permanent metal implants...

INTRODUCTION: Magnesium alloys are attractive as a class of biodegradable metallic materials. However, too fast degradation is an obstacle to their clinical applications. Recently, micro-arc oxidation (MAO) coatings were applied on biodegradable magnesium alloys to delay their degradation. In vivo studies showed that the protective ability of the MAO coating should be further improved [1]. Seal...

Magnesium alloys offer a favored alternative to steels and aluminum alloys due to their low density and relatively high specific strength. Their application potentials are, however, impeded by poor formability at room temperature. In the current work, improved formability for the commercial magnesium AZ80 alloy was attained through the application of the high-rate electro-magnetic forming (EMF)...
