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

“…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 . Among them, the nonisothermal crystallization behaviors and crystallization kinetics for MGs with various compositions, that is, multicomponent Zr‐Cu‐Fe‐Al MG, 15 Fe‐Co‐Cr‐Ni‐Zr MG, 16 Zr‐(CuAg)‐Al MG, 17 Fe‐Ni‐P‐B MG, 18 Zr‐Co‐Al‐Cu MG, 24 Fe‐Ni‐Mo‐P‐C‐B‐Cu MG, 25 Ti‐Zr‐Ni‐Cu‐Be MG, 26 Co‐Fe‐Ta‐B MG, 29 Ni‐Nb‐Ti‐Zr‐Co‐Ta MG, 31 Fe‐Cr‐P‐C‐B MG, 32 and Fe‐Co‐Cr‐Mo‐Y‐C‐B MG 33 ; ternary U‐Co‐Al MG, 19 La‐Al‐Co MG, 27 Zr‐Al‐Fe MG, 30 Zr‐Co‐Al MGs, 24,35 Fe‐P‐C MG, 36 Fe‐B‐C MG, 37 La‐Al‐Ni MG, 38 and Pd‐Ni‐P MG 39 ; and binary Cu‐Zr MG, 40 have been extensively researched by Kissinger, Ozawa, Kissinger‐Akahira‐Sunose (KAS), Ozawa‐Flynn‐Wall (OFW), and Vogel‐Fulcher‐Tammann (VFT) approaches using differential scanning calorimeter (DSC).…”

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

Tuning isothermal crystallization kinetics by minor similar solute element substitution in novel La‐(AlGa)‐C metallic glasses

“…Metallic glasses (MGs) are expected to be a noteworthy type of novel alloy attributed to the amazing properties, including prominent mechanical properties of high strength, hardness and wear resistance, superior corrosion resistance, and good soft‐magnetic properties, which can be employed as an innovative model material for scientific investigations and engineering applications 1–5 . It is universally known that MGs will instinctively change to a relative state such as the crystalline counterparts for their metastable nature, and this process can be stimulated at elevated temperatures, which exhibits remarkable effects on the structures and properties of MGs 6–11 . Accordingly, persistent efforts are required for knowing the crystallization kinetics of MGs under diverse conditions, which is of considerable benefit to the glass‐forming ability (GFA), structures, and properties of the MGs and developing more amorphous‐crystalline composites with desirable structures and properties 6–18 .…”

[6][7][8][9][10][11][12][13][14][15][16][17][18] Meanwhile, it is also suggested that the crystallization kinetics of MG systems is generally composition dependent, which will vary with the change in the composition of MGs.…”
