Thermal stability and non-isothermal crystallization kinetics of Ti41.5Cu42.5Ni7.5Zr2.5Hf5Si1 bulk metallic glass

Self-repair by stress-induced diffusion of noble elements during oxidation of Zr48Cu36Al8Ag8 bulk metallic glass

“…Among metallic glasses, in particular the Zr-based bulk metallic glasses (BMGs) possess a desirable combination of properties and high glass-forming ability (GFA), which makes them attractive for potential exploitation in various structural engineering applications [4,7,8]. Hitherto, most studies have focused on enhancing the plasticity [9][10][11][12], thermal stability [13][14] and GFA [15][16] of BMGs to improve their functional capabilities.…”

Amorphous and Nanocrystalline Metallic Alloys

“…Usually kinetic and structural criteria are also discussed [8][9][10]. Some alloys may be prepared as amorphous will have less cooling rate [11][12][13][14][15][16][17][18][19][20][21][22][23][24].…”

Investigation on Viscosity and Nonisothermal Crystallization Behavior of P-Bearing Steelmaking Slags with Varying TiO2 Content

“…With the wide use of differential scanning calorimeter (DSC) at crystallization study, several methods have been put forward to obtain kinetic parameters from non-isothermal experiments carried out at different cooling rates. [39][40][41] During the non-isothermal crystallization process, the relative degree of crystallinity can be determined by measuring the partial area of DSC peak. The relative degree of crystallinity α as a function of relative crystallization time can be theoretical estimated by means of the following equation: [42]…”

“…It is obviously observed that the t1 value decreased with increasing cooling rate, suggesting that the crystal grew faster when the cooling rate increased. In addition, the S-shape curves can be schematically divided into three regions, i.e., the random nucleus of crystal occurring at stage A, then the crystal growing rapidly at stage B and the coalescence of crystal happening at stage C. [41] Figure 7 (b) shows the crystallization time of primary crystals with the cooling rate of 10K/min. Compared with slag 1, it can be seen that the crystallization time of P1 for slag 2 with 3wt.% TiO2 has a slightly decrease.…”
