Controlling degradation of magnesium or its alloys in physiological saline solutions is essential for their potential applications in clinically viable implants. Rapid degradation of magnesium-based materials reduces the mechanical properties of implants prematurely and severely increases alkalinity of the local environment. Therefore, the objective of this study is to investigate the effects o...

Laser welding of dissimilar aluminium alloys with filler material Luís Filipe Amaro Pinto Instituto Superior Técnico – Technical University of Lisbon – Portugal September 2008 Abstract The aluminium alloys are materials with great potential because of its high strength and low weight. However, the welding of dissimilar aluminium alloys is difficult in autogeneous welding, due to these alloys ar...

Compared with traditional inorganic nonmetallic materials medical polymer materials, many advantages, such as better strength, toughness, fatigue resistance, easy processing. Its mechanical properties are suitable controllable. It can meet same elastic modulus, cell compatibility, biodegradability huma...

It is shown that the main modifiers of foundry magnesium alloys cannot create heterogeneous crystallization centers in melts during their solidification. Modification alloy structures an adsorption‑nanostructural process. adsorbed hydrogen a modifying element alloys. The mechanism modification consists large decrease concentration by significantly reducing dissolved hydrogen.
