Alloy design based on single-principal-element systems has approached its limit for performance enhancements. A substantial increase in strength up to gigapascal levels typically causes the premature failure of materials with reduced ductility. Here, we report a strategy break this trade-off by controllably introducing high-density ductile multicomponent intermetallic nanoparticles (MCINPs) complex alloy systems. Distinct from intermetallic-induced embrittlement under conventional wisdom,...
In order to study chemical complexity-induced lattice distortion in high-entropy alloys, the static Debye–Waller (D-W) factor of NiCoFeMnCr solid solution alloy is measured with low temperature neutron diffraction, ambient X-ray and total scattering methods. The atomic displacement parameter multi-element component at 0 K 0.035–0.041 Å, which obvious larger than that element Ni (∼ Å). pair distance between individual atoms investigated extended absorption fine structure (EXAFS) measurements...
Solid solution strengthening is the major mechanism that accounts for high strength of single-phase body-centered cubic (BCC) refractory high-entropy alloys (RHEAs). Local lattice distortion (LLD), often regarded as one core effects HEAs, generally believed to be deterministic in solid RHEAs since loosely packed BCC crystal structure can accommodate significant LLD. To systematically investigate effect LLD on strengthening, present study deliberately introduced different degrees...
