ALLOYS An alloy is a solid solution or homogeneous mixture of two or more elements, at least one of which is a metal, which itself has metallic properties. Alloying one metal with others often enhances its properties, especially strength. The physical properties, such as density, reactivity, Young''s modulus, and electrical and thermal conductivity, of an alloy may not differ greatly from those
The hodic reaction was considered as a three part sequence: (1) water dissociation, (2) hydrogen diffusion, and (3) hydrogen evolution. The water dissociation reaction became endothermic for Ge, In, Sb, and Sn dilute alloying, whereas Ca, Sc, Y, Ti, and Zr enhanced the already favorable water dissociation reaction.

ABSTRACT The grain refining technique of AZ91D magnesium alloy by MgCO 3 has been investigated. The refining mechanism and tensile properties of the resulting alloy have also been discussed. The results indie that MgCO 3 can decrease its grain size from 311 to 53µm. m.
Magnesium weight savings, on an equal strength basis, is approximately 25% vs. aluminum depending on alloy, which allows for longer flight range per gallon of jet fuel Increased cargo capacity With significantly lighter magnesium seats on the plane, more cargo weight capacity is available
The use of medical devices has hit an all-time high, with the global industry currently valued at $200 million and strong growth predictions through to 2023. 1 These devices include surgical implants, which cover a broad range of appliions such as artificial joints, lap-bands, stents, and pacemakers, with the goal of supporting tissue regeneration and providing optimal healing, allowing a
