The influences of temperature and microstructure on the tensile properties of a CoCrFeMnNi high-entropy alloy
Abstract An equiatomic CoCrFeMnNi high-entropy alloy, which crystallizes in the face-centered cubic (fcc) crystal structure, was produced by arc melting and drop casting. The drop-cast ingots wereExpand

Temperature dependence of the mechanical properties of equiatomic solid solution alloys with face-centered cubic crystal structures
Abstract Compared to decades-old theories of strengthening in dilute solid solutions, the mechanical behavior of concentrated solid solutions is relatively poorly understood. A special subset ofExpand

A fracture-resistant high-entropy alloy for cryogenic applications
A metal alloy that is stronger when cold Metal alloys normally consist of one dominant element, with others in small amounts to improve specific properties. For example, stainless steel is primarilyExpand

Influence of Ni on martensitic phase transformations in NiTi shape memory alloys
Abstract In the present paper we show how carbon affects martensitic transformations in Ni-rich NiTi shape memory alloys. During vacuum induction melting in graphite crucibles, NiTi melts dissolveExpand

The correlation of the indentation size effect measured with indenters of various shapes
Experimental results are presented which show that the indentation size effect for pyramidal and spherical indenters can be correlated. For a pyramidal indenter, the hardness measured in crystallineExpand

Microstructure evolution and critical stress for twinning in the CrMnFeCoNi high-entropy alloy
Abstract At low homologous temperatures (down to cryogenic temperatures), the CrMnFeCoNi high-entropy alloy possesses good combination of strength, work hardening rate (WHR), ductility, and fractureExpand

Relative effects of enthalpy and entropy on the phase stability of equiatomic high-entropy alloys
Abstract High configurational entropies have been hypothesized to stabilize solid solutions in equiatomic, multi-element alloys which have attracted much attention recently as “high-entropy” alloysExpand

Tensile properties of high- and medium-entropy alloys
Abstract Equiatomic, face-centered-cubic, high- and medium-entropy alloys were arc melted, hot-rolled to produce recrystallized sheets, and tensile tested. The alloys having the compositionsExpand

Exceptional damage-tolerance of a medium-entropy alloy CrCoNi at cryogenic temperatures
High-entropy alloys are an intriguing new class of metallic materials that derive their properties from being multi-element systems that can crystallize as a single phase, despite containing highExpand

Effects of pre-strain on the compressive stress-strain response of Mo-alloy single-crystal micropillars
A NiAl-Mo eutectic was directionally solidified to produce composites with well-aligned single-crystal Mo-alloy fibers embedded in a NiAl matrix. They were pre-strained by compressing along the fiberExpand
