    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Saad Ahmed Sheikh; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ductility; topologically closed-pack TCP and geometrically closed-pack GCP phase; alloy design; mechanical properties; High-entropy alloys; refractory high-entropy alloys; valence electron concentration;

    Abstract : High-entropy alloys (HEAs) are described as alloys containing multi-principal elements in equal or close to equal atomic percentage. HEAs are considered as potential structural materials for high-temperature applications; where alloy design and optimization of mechanical properties is extremely critical. READ MORE
