Abstract null null The crystallization in Cu15Zr85 amorphous film was studied by using molecular dynamics simulation in a wide annealing temperature region. The effect of annealing temperature on crystallization behavior was evaluated. The degree of crystallization increases firstly and then decreases with the increasing of annealing temperature in Cu15Zr85 amorphous film. A comparison of interior and Surface-A components shows that Surface-A component has higher crystallization rate at low anne...

Abstract null null The Ni-free Ti-based bulk metallic glasses (BMGs) with high glass-forming ability (GFA) can be synthesized in the (Ti, Cu, Zr)92.5Fe2.5Sn2Si1Ag2 alloy system over a wide composition range by copper-mold casting. Especially, the Ti48Cu37Zr7.5Fe2.5Sn2Si1Ag2 glassy alloy can form the BMG rod with a diameter up to 6 mm and showed a high compressive strength of ~ 2.05 GPa, elastic modulus of ~ 100 GPa, and microhardness of ~ 571 Hv. The Ti-based BMGs presented good bio-corrosion re...

Abstract null null The effect of primary α-Fe precipitation on thermal properties and magnetic properties was systematically investigated by fabricating Fe76.5-xCu1NbxSi13.5B9 (x=0, 1, 2 and 3) amorphous/nanocrystalline ribbons using melt-spinning method at different cool rate, which is controlled by wheel linear speed. It was found that the rapid quenching process shows similar influence on α-Fe precipitation to heat treatment. The as-spun amorphous/nanocrystalline ribbons obtained at 20 m/s sh...

Abstract null null Co-based metallic glasses with ultrahigh strength and high microhardness are regarded as ideal surface-coating materials to significantly improve hardness and wear resistance of substrate materials. In this paper, a Co-based amorphous powder with high glass-forming ability was prepared by gas-atomization technique. Then a large-area Co-based amorphous coating was fabricated from the powder by laser cladding technology. The effects of different laser parameters (i.e., laser sca...

Abstract null null Development of advanced metals materials with ultrahigh strength, large plasticity and high thermostability is one of the most attractive aims for materials researchers. Co-based bulk metallic glasses (BMGs) with the highest strength (up to 6 GPa) and special strength (up to 650 Nm/g) among all of metals materials so far we known have received extensive attentions. In this paper, a family of Co-Ta-B-Si BMGs with high glass-transition temperature (above 870 K), large compressiv...

Abstract null null Localized pulsed electrical discharge (PED) atomization is developed as a general route to fabricate ultrafine metallic glass powders with high purity and sphericity, which cannot be achieved by conventional techniques, like mechanical alloying, chemical reduction and water/gas atomization. The new atomization process starts with a localized melting on crystalline alloy surface by PED. During the melting process, multiple crystalline phases in the starting alloy are melted and...

Abstract null null Prediction of the phase constitution of the multi-principle elements alloys (MPEAs) with various element numbers is important for alloy design and performance optimization. Herein, valence electron density parameter, null null null null α null null null , is proposed as an improvement of the valence electron concentration by including the impact of atom volumes. The phase constitution of numerous MPEAs is well predicted by the priori α- null null null null null Δ null H null n...

Abstract null null In this paper, a soft-magnetic Fe40Co40Ni10Cr10 high entropy alloy (HEA) was designed and fabricated, and its microstructure, magnetic properties, corrosion resistance and mechanical properties have been systematically investigated. It is found that, this HEA is composed of single FCC structure and shows homogeneous compositional distribution. This HEA has good soft-magnetic properties as well as excellent corrosion resistance comparable to stainless steel. Besides, this HEA h...

Abstract null null A family of novel hierarchical porous metallic glasses decorated by Cu nanoparticles (PMGs & Cu-NPs) was synthesized through one-pot pulse anodization method on Zr65Cu22Al8Fe5 metallic-glass plates. The typical hierarchical porous morphology with two-levels pores in size of 9.74±2.4 μm and 1.41±0.41 μm was characterized for the samples pulse-anodized for 1800 s with a pulse period of 5 s etching and 10 s delay in 3.0 wt.% NaCl solution. Plenty of in-situ Cu nanoparticles in th...
