This study proposes a new methodology for producing metal matrix nanocomposites in the solid state. The process involves the plasma‐assisted thermochemical treatment of metallic alloy powders. As a proof‐of‐concept, TiN nanoparticles are synthesized directly on the surface of FeTi intermetallic powder particles, enabling the development of the ...

Advanced DC-DC power conversion topologies and mathematical analytical methods [PDF]
224 p. In modern technology, power conversion equipment is very important and is now used in a great variety of products. The corresponding equipment can be divided into four groups, ac-ac converters, ac-dc rectifiers, dc-dc converters, dc-ac inverters. From recent reports, the production of dc-dc converters occupies the largest percentage of the total

Bimetallic (NiFe) and trimetallic (NiFeCr) nanoalloys (NAs) are synthesized using corresponding oxide mixtures using microwave hydrogen plasma within a few milliseconds. The process simultaneously 1) reduces metal oxides to metals; 2) downsizes the particles from micrometers to nanometers; and 3) blends the metals to form NAs.
