Nanostructure, mechanical and tribological properties of reactive magnetron sputtered TiCx coatings
(2008)
This study describes the correlation between microstructure, mechanical and tribological properties of TiCx coatings (with x being in the range of 0–1.4), deposited by reactive magnetron sputtering from a Ti target in ...
Mechanics and energetics modeling of ball-milled metal foil and particle structures
(2017)
The reported research establishes a semi-analytical computational predictive model of fractal microstructure in ball-milled metal foils and powder particulates, with emphasis on its transformation mechanics via an energy-based ...
Exothermic reaction characteristics of continuously ball-milled Al/Ni powder compacts
(2013)
Self-propagating reactions in compacted pellets of continuously low-energy ball-milled aluminium (Al) and nickel (Ni) powders at a composition corresponding to AlNi3 were investigated. The formation of a bi-modal structure ...
Spark ignitable ball milled powders of Al and Ni at NiAl composition
(2014)
Low-energy ball milling of aluminum and nickel particles with an overall composition corresponding to the NiAl intermetallic phase was performed up to milling durations of 13 h. The milled powders and cold-compacted pellets ...
Synthesis of reactive Al/Ni structures by ball milling
(2010)
Material systems that exhibit self-propagating exothermic reactions (SPER) can be potentially used for nano/microscale heater purposes in thermal nanomanufacturing applications. We propose that ball milling (BM) is a simple ...
The influence of structure on thermal behavior of reactive Al–Ni powder mixtures formed by ball milling
(2010)
Ball milling (BM) was used to produce reactive Al–Ni powder mixtures that exhibit self-propagating exothermic reactions (SPER) for nano–micro heater applications. Powders with an Al–Ni molar ratio of 1:3 were milled, cold ...
Fabrication of nanorods by metal evaporation inside the pores of ultra-thin porous alumina templates
(2007)
Porous alumina has attracted a great deal of attention as a template material for the growth of nanowires and nanodots. Typically, the pores have a high aspect ratio, which forbids the use of evaporation techniques for ...
Modeling of the self-propagating reactions of nickel and aluminum multilayered foils
(2009)
In this study, we performed simulations of self-propagating reactions of nanoscale nickel-aluminum multilayers using numerical methods. The model employs two-dimensional heat transfer equations coupled with heat generation ...
