Microstructure Development and Properties of the Two-Component Melt-Spun Ni55Fe20Cu5P10B10 Alloy at Elevated Temperatures

“…One of the ways to achieve the goal of controlling the microstructure of the element in order to obtain the appropriate performance characteristics is to produce a composite composed of materials with different properties. There are reports on the production of amorphous-amorphous and amorphous-crystalline materials [ 1 , 2 , 3 , 4 , 5 , 6 ] and works on controlling the phase composition and properties of these materials [ 7 , 8 , 9 , 10 ]. Among the methods of producing amorphous composites, technologies based on the production of powders and their amorphization are also used [ 11 , 12 , 13 , 14 ].…”

Nonisothermal crystallization kinetics of Cr‐rich metallic glass Cr29.4Fe29.4Mo14.7C14.7B9.8Y2 with desirable properties

“…As a promising type of advanced materials, Cr‐bearing metallic glasses (MGs) have gained extensive attentions attributing to the combination of attractive properties, that is, remarkable corrosion resistance, high thermal stability, high strength, high hardness, and wear resistance, which makes them as prospective materials for scientific investigations and engineering applications 1–14 . However, it is unavoidable that MGs will change into the corresponding crystalline counterparts for their metastable nature and this can be enhanced with increasing temperatures, which exhibits noticeable effects on their structures and properties 15–19 . Therefore, it is essential to investigate the crystallization behaviors and crystallization kinetics of MGs at various heating conditions, which is significant for tuning the structures and properties of MGs 15–40 .…”

Under nonisothermal crystallization conditions, MGs were continuously heated up to complete crystallization by different heating rates.…”

“…On the basis of this, the local Avrami exponent, activation energy, and the kinetic fragility parameter under nonisothermal crystallization conditions can be obtained, which is crucial for pointing out the nonisothermal crystallization mechanism and tuning the structures and properties of MGs. [15][16][17]24,26,29 Previously, a novel Cr-rich MG Cr 29.4 Fe 29.4 Mo 14.7 C 14.7 B 9.8 Y 2 (at.%) was developed with desirable advantages, such as good glass-forming ability (GFA) with a critical dimeter of 3 mm, high thermal stability with the glass transition temperature (T g ) of 936 K and the supercooled liquid region (ΔT x ) of 79 K, prominent corrosion resistance of no weight loss after immersion in 1 M HCl solution, high fracture strength up to 3.91 GPa and high Vickers microhardness up to 13.66 GPa. Consequently, it is considered as promising corrosion/wear resistance coating materials to enrich the potential application of MGs.…”
