چکیده
In this paper, molecular dynamics simulation method was used to establish the atomic model of high entropy alloy. The effect strain rate on microstructure evolution and dislocation motion FeNiCoCrCu alloy studied by applying tension compression loads at different rates. results show that stress–strain curve presents three stages elastic deformation, yield plastic deformation under rate. Under tensile load, Frank causes material, reaction between Shockley Hirth generates Stair-rod dislocation. mechanism stress relaxation materials load is formation stacking faults. One mechanisms hardening twins. addition, faults intersect with each other produce reactions, which generate dislocations, maintaining development effect.

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...

The high entropy alloy containing refractory metals Mo-Nb-Ta-W has a body centered cubic structure, which is not surprising given the complete mutual solubility in BCC solid solutions of all pairs of the constituent elements. However, first principles total energy calculations for the binaries reveal a set of distinct energy minimizing structures implying the likelihood of chemically ordered lo...

High-entropy alloys (HEAs) are promising structural materials due to their excellent comprehensive performances. The use of mechanically alloyed powders to deposit HEA coatings through atmospheric plasma spraying (APS) is an effective approach that can broaden the application areas of the HEAs. In this paper, a ductility-brittleness AlCoCrFeNiSi system was chosen as an object of study, and the ...
