While the mechanical properties of stoichiometric B2 β-phase NiAl are well established, effect off-stoichiometric composition on fracture behavior has not yet been systematically studied over entire range 40-55% Al. Here we use microbending tests notched cantilever beams FIB-milled from single crystals with an aluminized as oxidation-induced gradient to determine influence Al concentration toug...

We study the electronic and transport properties of artificial Au atomic chains on a NiAl(110) surface template using state-of-the-art first principles calculations. Au chains display remarkable one-dimensional electronic properties that can be tuned by the selective adsorption of small molecules: a single CO group is shown to modulate the electronic wave functions, acting as a "chemical scisso...

Resistance spot welding (RSW) is widely used as a main joining technique in industry and the electrode caps are frequently replaced because of degradation during service. In this study, G type copper RSW were coated with Fe Ni based Fe3Al, FeAl, Ni3Al, NiAl alloys by Electro-Spark Deposition (ESD), providing resistance to hot deformation, oxidation Zn evaporation from sheet metal. The ESD teste...
