high-entropy alloydual phase composite structureultrasonic vibrationWe successfully fabricate high-entropy alloys and amorphous alloy composites by adopting the proposed ultrasonic vibration method. The low-stress, low-temperature method enables us to create composites that combine both amorphous and ...
Chemical and topological parameters have been widely used for predicting the phase selection in high-entropy alloys (HEAs). Nevertheless, previous studies could be faulted due to the small number of available data points, the negligence of kinetic effects, and the insensitivity to small compositional...
Keywords: Amorphous; High entropy alloys; Crystallization; Phase selection; Miedema’s model We believe Amorphous-High entropy alloy (HEA) composites might provide high toughness in line with the metallic glass-solid solution composites developed by Johnson and co-workers [1,2]. Formation of ...

Phase stability is an important topic for high entropy alloys (HEAs), but the understanding to it is very limited. The capability to predict phase stabilit... Sheng GUO;C.T.LIU Center of Advanced Structural Materials;MBE Department;City University of Hong Kong;Kowloon;Hong Kong;China; 被引量...
High-entropy amorphous alloys present high hardness, but low tensile ductility. Here, deformation behavior of the amorphous/crystalline Fe Co Cr Ni high-entropy alloy(HEA) composite prepared by the previous experiment is investigated using atomic simulations. The result shows the partial dislocations ...
The paper makes a review about the opportunity, forming conditions and obtaining methods of bulk amorphous alloys and their properties. There are also pres... Viorel Aurel erban,C Codrean,Ion Drago Uu - 《Key Engineering Materials》 被引量: 2发表: 2009年 A Lightweight AlTiVNb High-Entropy ...
The alloy design for equiatomic multi-component alloys was rationalized by statistically analyzing the atomic size difference, mixing enthalpy, mixing entropy, electronegativity, valence electron concentration among constituent elements in solid solutions forming high entropy alloys and amorphous alloys. Solid ...
Influence of the phase composition on the magnetic properties of the alloys has been established. It is shown that the formation of a nanosized eutectic structure [α + (Fe,Cr)3B] upon the crystallization of an amorphous matrix is promising for the development of new hard magnetic materials. ...
Metallic glasses present remarkable and distinguished attributes compared to conventional alloys [1,2]. Among most of bulk metallic glass (BMG) systems, Fe-based ones are interesting to be used as protective materials because they present elevated crystallization temperature, high hardness, and excellent...
