3D ink-extrusion additive manufacturing of CoCrFeNi high

Introduction. Fabrication of engineering parts from high-entropy alloys (HEA) using additive manufacturing (AM) has been increasingly studied in the past five years 1 3.Initial studies focused on powder bed fusion of CoCrFeNi, a prototype single-phase high entropy alloy with face-centered-cubic (fcc) structure 4, from pre-alloyed powders, and observed increased strength and ductility A Review on Grain Refinement of Aluminum Alloys Its long-term goal was to develop metals and metal-based matrix composites with high strength, high ductility, corrosion and wear resistance and to give priority to improve the strength, formability and corrosion resistance of 2, 5, 6 and 7 series aluminum alloys as well as to expand the use of heat-resistant aluminum alloys .

Achieving High Strength and High Ductility in

Ultrafinegrained materials may be produced by applying severe plastic deformation, but these materials generally exhibit high strength and limited ductility.This report describes a technique for producing high strength and high ductility (see Figure) in precipitationhardened alloys at ambient temperatures based on introducing intermediate metastable phases into ultrafinegrained BHARAT GWALANI - Staff Scientist - Pacific Northwest A significant increase in compressive yield strength of the Al0.3CoCrFeMnNi high-entropy alloy (HEA) from 979 MPa to 1759 MPa was observed upon the introduction of 3 vol.% Y2O3. Deep Choudhuri - Google Scholar CitationsTensile yield strength of a single bulk Al0.3CoCrFeNi high entropy alloy can be tuned from 160 MPa to 1800 MPa B Gwalani, S Gorsse, D Choudhuri, Y Zheng,

Effect of cooling rate on microstructure and mechanical

Feb 20, 2019 · The influence of cooling rate on the microstructure and mechanical properties of Al 0.3 CoCrFeNi high-entropy alloys was systematically investigated. By adjusting preparation methods and the size of the alloys, three cooling rates, ~2.5 K s 1, ~40 K s 1 and ~10 3 K s 1, were achieved.The alloys were monophasic and retained the FCC structure under the three cooling rates, whereas a Enhanced strength and ductility of Al0.9CoCrNi2.1 eutectic May 01, 2020 · After annealing for the cold-rolled alloy, a balanced strength and ductility is achieved, with a yield strength, ultimate strength and total elongation of 820 MPa, 1400 MPa and 11.6%, respectively. In contrast with the as-cast properties, the annealed alloy exhibits a simultaneous strength-ductility enhancement. Exceptional cryogenic strength-ductility synergy in Al0 We engineered an Al0.3CoCrNi medium-entropy alloy with heterogeneous grain structure and nanoscale precipitation through thermo-mechanical processing route, with an aim to achieve a

Fully Recrystallized Al0.5CoCrFeNi High-Entropy Alloy

The correlation among the strength, ductility and precipitates in a dual-phase Al0.5CoCrFeNi high-entropy alloy has been investigated. The property of plastic was improved in the recrystallized Managing Both Strength and Ductility in Duplex Stainless In this paper, we engineered Al0.3CoCrNi medium-entropy alloy to contain multi-phase hierarchical microstructure and demonstrated a high yield strength of 1 GPa, a high tensile strength of Microstructure and wear resistance of the laser-cladded Feb 10, 2020 · Because of its high specific strength, good weldability, and other advantages, the aluminum (Al) alloy has become a popular choice for manufacturing lightweight equipment [1, 2].However, the low hardness and poor wear resistance of the Al alloy surface limit its applicability in high-end manufacturing industries exhibiting high reliability requirements.

WO2003104505A2 - Nanophase precipitation strengthened

Aluminum alloys having improved strength characteristics at elevated temperatures (300°C) are manufactured by combining selected transition metals (Ni, Co, Ti, Fe, Y, Sc) and selected rare earth materials (Er, Tm, Yb, Lu) in amounts of about 2 to 12% and 2 to 15% atomic percent respectively in an amorphous, glassy state and subsequently devitrifying the amorphous material to form a Achieving High Strength and High Ductility in Ultrafinegrained materials may be produced by applying severe plastic deformation, but these materials generally exhibit high strength and limited ductility.This report describes a technique for producing high strength and high ductility (see Figure) in precipitationhardened alloys at ambient temperatures based on introducing intermediate metastable phases into ultrafinegrained
