27Al NMR measurement of fcc Al configurations in as-quenched Al85Ni11Y4 metallic glass and crystallization kinetics of Al nanocrystals

Non-isothermal crystallization kinetics and glass-forming ability of Cu–Zr–Ti–In bulk metallic glasses

“…In the past two decades, a great deal of efforts have been contributed to the investigation of crystallization kinetics for understanding the thermal stability and microstructural evolution [7][8][9][10][11]. Johnson-Mehl-Avrami (JMA) equation (x(t) = 1 − exp[−k(t − ) n ], where x, t, k, and n are the crystallized volume fraction, time, the effective overall reaction rate constant and Avrami exponent, respectively.)…”

A calorimetric study of thermodynamic properties for binary Cu–Ge alloys

“…Meanwhile, the DSC heating-cooling curves provide the essential information on phase transformation characteristics [3,[29][30][31][32]. The objective of this work is to determine the phase transformation temperatures and enthalpy of fusion for Cu-Ge alloys by DSC method.…”

Abnormal crystallization behavior of an (Al86Ni9La5)98Si2 amorphous alloy

“…(7) shows that the rate of change of T p with heating rate, dT d P β , is always larger than zero as β, T p , R and E are always positive. The peak temperature therefore increases with increasing heating rate.…”

“…It is unfortunate that such interesting and important properties associated with this glassy structure may be lost as a result of crystallization [4]. A great deal of effort has been devoted to understanding the thermal stability and microstructural evolution of amorphous alloys over the past few decades [5][6][7][8]. It is often observed that two or more crystallization events can occur almost simultaneously in some amorphous alloys during isochronal annealing at certain heating rates [9,10], as revealed by overlapping exothermic peaks in a differential scanning calorimetry (DSC) thermal analysis curve.…”
