Mechanical alloying of Mg2Si

Scripta Metallurgica et Materialia, 1995
Mg{sub 2}Si is an intermetallic compound with low density (1.95 gcm{sup {minus}3}) and a rather high melting point (1,087 C). Due to its lightweight and thermophysical properties it is suitable for structural applications. It is also promising as a basic material for the thermoelectric energy conversion. A problem is its synthesis because magnesium and

The mechanism of mechanical alloying

Metallurgical transactions, 1974
The mechanical alloying process is a new method for producing composite metal powders with controlled microstructures. It is unique in that it is an entirely solid state process, permitting dispersion of insoluble phases such as refractory oxides and addition of reactive alloying elements such as aluminum and titanium.

ALLOY PHASE FORMATION BY MECHANICAL ALLOYING: CONSTRAINTS AND MECHANISMS

Modern Physics Letters B, 1992
Alloy phase formation in binary metallic systems by mechanical alloying (MA) of elemental powders is briefly reviewed. Our recent results indicate the inadequacy of the current understanding of the MA process, which has been depicted as an isothermal solid-state interdiffusion reaction under interfacial, metastable, equilibrium in layered composites ...

Mechanical behavior and properties of mechanically alloyed aluminum alloys

Metallurgical and Materials Transactions A, 1996
The fracture and deformation behaviors of several product forms produced from mechanically alloyed (MA) aluminum alloys 9052 and 905XL were studied. The main operative strengthening mechanism is strengthening due to the submicron grain size. Ductility and toughness were found to be controlled by the morphology of the prior particle boundaries.

Mechanisms of Mechanical Alloying

1998
Unlike conventional processes in which materials are produced either by melting or sintering at high temperature, synthesis of different types of materials using the mechanical alloying or milling process is generally carried our at room temperature although temperature may rise during milling.

Mechanics of Quasi-Periodic Alloys

Journal of Nonlinear Science, 2005
A general description of the nonlinear mechanical behavior of quasi-periodic alloys is presented: It accounts for the rearrangements of atomic clusters (phason activity) and is based on a Lagrange-d'Alambert-type principle where phason dissipative effects are included.

Aluminium Alloys by Mechanical Alloying

Aircraft Engineering and Aerospace Technology, 1987
After years of research, an important development in powder metallurgy is about to enter commercial production with the commissioning by Inco Alloys International of its $4 million plant in Pittsboro, North Carolina, to produce aluminium and other light metal alloys by mechanical alloying.

Corrosion Mechanisms of Magnesium Alloys

Advanced Engineering Materials, 1999
The high strength to weight ratio of magnesium alloys makes them extremely attractive for applications in transport or aerospace technology. However, their corrosion behavior is a major issue and one reason why they are still not as popular as aluminum alloys.

Diffusion mechanisms in amorphous alloys

Materials Science and Engineering, 1988
Abstract A critical analysis of experimental data shows that self-diffusion in relaxed amorphous alloys is controlled by mechanisms involving collective thermal activations. Whereas in FeZr alloys both 59Fe and 95Zr diffuse via direct mechanisms that change with the alloy composition (e.g.
