AlxCrFeNi medium entropy alloys with high damping capacity
Journal of Alloys and Compounds, 2021Abstract In this paper, the phase constituent, damping and compressive properties of as-cast AlxCrFeNi (x = 0.3, 0.35, 0.37, 0.4, 0.5) medium entropy alloys (MEAs) were studied. The results show that the phase constituent changes gradually from a face-centered cubic (FCC) dominated structure to a single body-centered cubic (BCC) structure when x ...

Plastic deformation mechanism of CoCrxNi medium entropy alloys
Materials Science and Engineering: A, 2021Abstract The mechanical properties of multi-principal element alloys show a big difference with or without Cr additions. In this work, the roles of Cr on the mechanical properties, especially the plastic deformation mechanism of CoCrxNi alloys are systematically investigated.

Microstructural Characterization of Medium Entropy Alloy Thin Films
SSRN Electronic Journal, 2019This study presents detailed microstructural investigations on single and bilayer thin films of two medium entropy alloys (MEAs) synthesized using magnetron sputter deposition. Single layer thin films of CoCrFeNi and AlCoCrFe show single-phase face-centered cubic (fcc) and body-centered (bcc) structure, respectively. The bilayer thin film consisting of

Kinking in a refractory TiZrHfNb0.7 medium-entropy alloy
Materials Letters, 2020Abstract As a type of cooperative deformation like twinning, kinking can improve the deformability of materials by stress relaxation and crystal reorientation. In this work, kinking with 〈0 1 1〉 lattice rotation axis was identified in a refractory TiZrHfNb0.7 medium-entropy alloy (MEA).

Design of high-ductile medium entropy alloys for dental implants
Materials Science and Engineering: C, 2020Developing new materials with high strength and ductility, low modulus and high biocompatibility is a continuing demand in the field of surgical implants. Inspired by the high-entropy design philosophy, two medium entropy alloys (MEAs), i.e. equiatomic TiZrHf and equi-weight Ti40Zr20Hf10Nb20Ta10 were designed and their mechanical properties and ...

Composite of Medium Entropy Alloys Synthesized Using Spark Plasma Sintering
SSRN Electronic Journal, 2020Abstract A composite of two different medium entropy alloys (MEAs, i.e., CoCrFeNi and AlCoCrFe) was synthesized using ball milling and spark plasma sintering. The composite microstructure contains a homogenous distribution of fcc and bcc phases with submicron-sized grains and exhibits excellent microstructural and phase stability even after 100 h ...
