Defects in Thin Layers of High Entropy Alloy HfNbTaTiZr

Thermal stability of AlCoCrCuFeNi high entropy alloy thin films

High entropy alloys (HEAs), containing five to thirteen metallic elements, with a concentration in the range of 5 to 35 % for each element, exhibit very interesting properties (mechanical, tribological, formability, magnetism...). Their high mixing entropy promotes the formation of simple solid solutions with amorphous or nanocrystallized structure. Bulk pieces of these alloys are known to be s...

Polymorphism in a high-entropy alloy

Polymorphism, which describes the occurrence of different lattice structures in a crystalline material, is a critical phenomenon in materials science and condensed matter physics. Recently, configuration disorder was compositionally engineered into single lattices, leading to the discovery of high-entropy alloys and high-entropy oxides. For these novel entropy-stabilized forms of crystalline ma...

Molecular dynamics simulation of Al–Co–Cr–Cu–Fe–Ni high entropy alloy thin film growth

Metallurgical and mechanical properties of laser cladded AlFeCuCrCoNi-WC10 high entropy alloy coating

In spite of excellent corrosion resistance, good ductility and low cost of AISI 316 austenitic stainless steel, the low hardness and poor mechanical charecteristic of material restricts its applicability in several industrial services. To improve upon mechanical properties AlFeCuCrCoNi-WC10 high-entropy alloy coatings were deposited via laser cladding on austentic stainless steel AISI 316 subst...

Slip nucleation in single crystal FeNiCoCrMn high entropy alloy

a r t i c l e i n f o We present an experimental and theoretical study of slip nucleation in high entropy FeNiCoCrMn alloy which possesses superb mechanical properties. Uniaxial compression experiments were conducted on the ½591Š oriented single crystals. The single crystals permit evaluation of critical resolved shear stress (CRSS), and using Digital Image Correlation strain measurements it is...
