Crystallization Kinetics Study in Al87Ni10La3 Amorphous Alloy
In this study, the crystallization behavior of melt-spun Al87Ni10La3 amorphous phase was investigated by using X-ray diffraction and non-isothermal differential thermal analysis techniques. The results demonstrated that the amorphous phase exhibited two-stage crystallization on heating, i.e., at first step the amorphous phase transforms into α-Al phase and at second step Al11La3 and Al3Ni inter...
متن کاملNon-isothermal Primary Crystallization Kinetics of the Amorphous Fe85.3B11P3Cu0.7 Alloy
In the present research, the primary crystallization kinetics of the amorphous Fe85.3B11P3Cu0.7 alloy was analyzed using non-isothermal DSC measurements. The average and local activation energies, Ea, were determined by different isokinetic and isoconversional methods. The results obtained for activation energy in this research, show that due to the complexity of the primary crystallization pro...
متن کاملMagnetic Properties and Crystallization Kinetics of a Mn-Doped FINEMET Precursor Amorphous Alloy
The kinetics of nanocrystallization of a Mn-doped FINEMET alloy from its amorphous precursor is reported. The alloy studied was of a composition (Fe1 Mn )73 5Nb3CuSi13 5B9 where = 0 05. X-ray diffraction (XRD) confirmed that -FeSi is the product of primary nanocrystallization. Crystallization kinetics were studied using time-dependent magnetization, ( ), as a measure of the volume fraction crys...
متن کاملThermal, Magnetic, and Structural Characterization of the Crystallization Kinetics of Amorphous Soft Magnetic Materials
Introduction An understanding of the crystallization kinetics of magnetic amorphous alloys is of scientific interest for two important reasons. First, for an alloy that exhibits excellent magnetic properties in its amorphous phase, the crystallization kinetics represent the limit at which these properties begin to deteriorate. Therefore, thermal stability determines the magnetic stability of th...
متن کاملThe Thermal, Magnetic, and Structural Characterization of the Crystallization Kinetics of Fe88Zr7B4Cu1, An Amorphous Soft Magnetic Ribbon
The characterization of the crystallization kinetics of an amorphous soft magnetic alloy, Fe88Zr7B4Cu1, called NANOPERM, is presented. Vibrating sample magnetometry (VSM), X-ray diffractometry, and differential scanning calorimetry have been used to observe crystallization kinetics. The VSM observations take advantage of the Curie temperature of the amorphous phase c amorphous of the NANOPERM a...
