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 ...
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 ...
