Rare Metals, EarlyView.ABSTRACT High‐entropy alloys (HEAs) have emerged as a transformative class of materials distinguished by their complex chemical compositions, unique microstructures, and remarkable mechanical and functional properties. Traditionally, the discovery and optimization of HEAs have relied on conventional methods, including trial‐and‐error experimentation ...

Microstructure and corrosion properties of SiC/Al-Mg-Cu-Si-Sn composites
Science and Engineering of Composite Materials, 2017 The SiC/Al-Mg-Cu-Si-Sn composites with different quantities of SiC particles by volume were fabricated using hot-pressing sintering. The effects of SiC volume fraction on the microstructure, Vickers hardness, and corrosion behavior of the composites were

Rare Metals, EarlyView.ABSTRACT Tungsten is inherently brittle and particularly prone to thermal stress concentration and crack formation during additive manufacturing processes such as laser cladding, which severely limits its engineering applications as a coating material. To address this issue, this study proposes an in situ toughening strategy involving the introduction ...

Hardness of CaF2 and BaF2 solid lubricants at 25 to 670 deg C [PDF]
Plastic deformation is a prominent factor in determining the lubricating value of solid lubricants. Little information is available and its direct measurement is difficult so hardness, which is an indirect measure of this property was determined for ...

Oxidation-induced changes in mechanical properties of silicon nitride ceramics [PDF]
, 1999 The effect of oxidation on the room-temperature mechanical properties of four different silicon nitride ceramics is investigated. The strength and the elastic modulus of the whole material and the hardness, the fracture toughness and the elastic ...

Rare Metals, EarlyView.ABSTRACT Internal oxidation has been identified as an effective method for enhancing the strength of AgMg alloys. However, the concurrent occurrence of embrittlement remains inadequately understood, thus limiting their broader application. This study investigates the oxidation behavior of AgMg alloys with Mg concentrations ranging from 1 at% to 7 at ...
