A Direct Extension of the Avrami Equation to Describe the Non-isothermal Crystallization of Al-base Alloys
(Elsevier, 2007)
A direct extension of the Avrami equation considering the temperature dependence of the frequency factor is applied to describe the crystallization of a series of Al-Mm-Ni-Co amorphous alloys (Mm is a mischmetal). For high ...

Specific Heat Measurements on Amorphous and Nanocrystalline Al88Y5Ni5Co2
(Elsevier, 2009)
Specific heat at constant pressure, CP, was measured on amorphous and nanocrystalline Al88Y5Ni5Co2 alloys from differential scanning calorimetry experiments. Linear behavior of CP versus temperature from 323 to 423 K is ...

Thermal and Microstructural Stability of the Soft Magnetic Fe60Co18Nb6B15Cu1 alloy
(Elsevier, 2007)
Temperature evolution of the coercivity of nanocrystalline samples of Fe60Co18Nb6B15Cu1 alloy with different crystalline fractions was measured from room temperature up to 690 K. Although room temperature coercivity increases ...

High Temperature Coercivity of Nb-containing HITPERM Alloys: Effect of Cu Addition
(Elsevier, 2008)
Hysteresis loops of nanocrystalline samples of Fe39Co39Nb6B16 - yCuy (y = 0, 1) HITPERM-type alloys were measured from room temperature up to 773K. The alloy with Cu shows a nearly constant value of coercivity (∼ 135A/m) ...
