METAL/METAL ARTICULATING INTERFACES
Orthopedics, 1995Polyethylene wear can be shown as a problem in long-term joint replacement. Metal-on-metal bearing is solving this problem, as long-term clinical and experimental investigations demonstrate. To avoid the problem of high friction found in old series, a new Metasul called technique with a smaller diameter was invented.

Current Opinion in Solid State and Materials Science, 1995
Amorphous metallic alloys, relative newcomers to the world of glasses, have properties that are unusual for solid metals. The metallic glasses, which exist in a very wide variety of compositions, combine fundamental interest with practical applications. They also serve as precursors for exciting new nanocrystalline materials.

Science, 1975
The novel internal structures of metallic glasses lead to exceptional strength, corrosion resistance, and ease of magnetization. Combined with low manufacturing costs, these properties make glassy ribbons attractive for many applications. These materials also have scientific fascination because their compositions, structures, and properties have ...

Metal-on-metal Bearing Surfaces
Journal of the American Academy of Orthopaedic Surgeons, 2009Metal-on-metal bearing couples remain a popular option in total hip arthroplasty and are the only currently available option for surface replacement arthroplasty. In general, the intermediate-term clinical performance of metal-on-metal bearings has been favorable.

The Chemical Record, 2010
AbstractThe synthesis and isolation of stable bimetallic complexes that contain formally quintuply bonded transition metals is a novel and emerging field of science. Efforts have been undertaken in designing and tuning the ligands to achieve a very short (actually the shortest) metal‐metal bond.

Deformation Processed Metal–Metal Composites
Advanced Engineering Materials, 2000Deformation processed metal–metal composites (DMMCs) are composites in which both the matrix and the reinforcing phase are ductile metals. The ductility of the metals permits the composite to be heavily deformed by drawing or rolling to reduce the thickness and spacing of the two phases to as small as 10 nm.

Ugeskrift for Læger, 2014
In Denmark 4,456 metal-on-metal (MoM) hip prostheses have been implanted. Evidence demonstrates that some patients develope adverse biological reactions causing failures of MoM hip arthroplasty. Some reactions might be systemic. Failure rates are associated with the type and the design of the MoM hip implant.

1985
An introduction to metal-metal superlattices is presented, along with a brief review of some of the materials which have been made, and phenomena which have been observed so far. We describe in detail the results of a number of structural characterization techniques applied to these materials, including Bragg θ-2θ x-ray diffraction, transmission and ...
