Reactive processing of nanostructured nickel aluminide intermetallics starting from elemental nanopowders

Development and characterization of bronze-Cr-Ni composites produced by powder metallurgy

“…Another significant feature is the ability to produce near net shape parts, which is cost effective [9] . Some materials, such as electrical contact materials [10,11] , copper alloys [12] , metal matrix composites [13,14] and most intermetallics [15] can be produced successfully via the PM technique.…”

Electrochemical behavior of Ni3Al-based intermetallic alloys in NaOH

“…Recently, refinement of grain sizes to nanometer dimensions was proposed as an excellent method to change considerably the properties of Ni 3 Al intermetallics. For example, in nanocrystalline ordered Ni 3 Al intermetallics, good ductility at room temperature [39], superplasticity [40e43] and a 200% increase in the microhardness [44] were observed.…”

Preparation and characterization of reactively sintered Ni3Al–hBN–Ag composite coating on Ni-based superalloy

“…mental effect [10][11][12], which severely restricts their use as coating materials. For overcoming these detrimental characteristics, one ideal approach is reactive sintering process [13][14][15][16][17][18][19]. This is because reactive sintering process is cost-effective and characterized by reduced intermetallics preparation time, and it is convenient to use reactive sintering process to admix elemental alloying additions [14][15][16] or ceramic reinforcements [17][18][19] into the composite materials for alloying or microstructural control so as to improve the properties of the Ni 3 Al intermetallic compound materials by attendant in situ reaction.…”
