Material Design for Enhancing Toughness of Mg Alloy and Application for Biodegradable Devicestal structure, however, limits the movement of some slip systems; therefore, pure magnesium possesses poor ductility and/or toughness. A number of studies have revealed that alloying with solute elements and modification of grain structure improved these drawbacks. In this study, to clarify the effe

Strengthening and Toughening Behaviors of the Mg–9Al Alloy Containing Oxygen Atomsof TiO. nanoparticles in the Mg–9Al alloy melt. The dissolved oxygen atoms expand the lattice structures of both α-Mg and β-phase, inducing the reduced mismatch distance between α-Mg and β-phase. Therefore, yield stress of the Mg–O–9Al alloy is 143 MPa, much higher than 110 MPa in the Mg–9Al alloy.

Investigations on Microstructure and Mechanical Properties of Non-flammable Mg–Al–Zn–Ca–Y Alloysral materials such as aluminium alloys. Nevertheless, magnesium still shows some major drawbacks e.g. high oxidation tendency and more expensive processing compared to aluminium alloys. By adding calcium and yttrium to the commercially dominating AZ alloys, the oxidation behavior can be significantl

In this vein, social agency is often ascribed to an organised version of society. A narrow definition of civil society seems to have become th
