Ni3AlReternary interdiffusionTernary interdiffusion in L12-Ni3Al with ternary alloying addition of Re was investigated at 1473K using solid-to-solid diffusion couples. Interdiffusion flux of Ni, Al, and Re were directly calculated from experimental concentration profiles and integrated for the ...

Using atomistic simulations, the authors evaluate the activation barrier for a screw superdislocation to form the Paidar–Pope–Vitek (PPV) locked configuration when intersecting a forest dislocation in L12 Ni3Al, as a function of the superpartial core width. It is shown that the PPV lock is ...
The site substitution behavior of Cr and Ta in the Ni3Al (L12)-type γ′-precipitates of a Ni–Al–Cr–Ta alloy is investigated by atom-probe tomography (APT) and first-principles calculations. Measurements of the γ′-phase composition by APT suggest that Al, Cr, and Ta share the Al ...
我怀疑你理解错了，多晶体的塑性变形需要5个独立的滑移系相互协调。Ni3Al虽是面心立方结构，滑移系的...

The quantitative and temporal-evolutional advantages of the microscopic phase field are used to study the lattice defects of the L12–Ni3Al(γ′) phase in a ternary Ni–Al–V system. The temporal evolutional process of the occupancy of each individual atom conforms to classical nucleation ...
