Abstract

This work studied the influence of thermomechanical treatment on the mechanical properties, structure, and crystallization of the Zr65.5Ni16Cu8.5Al10 metallic glass alloy. It established that thermomechanical treatment significantly affects the mechanical properties of the alloy while maintaining its amorphous structure due to the formation of regions of chemical inhomogeneity in the amorphous matrix. In addition, shear deformation affects the initial crystallization of the alloy. As a result, there is a transition from one-stage crystallization to two-stage crystallization with a strain increase.

Abstract

In this work, magnetically soft amorphous alloys of the Fe–Ni–P–B–Si–C system. The crystallization kinetics of alloys has been investigated different thermal analysis by means of isothermal heating and continuous heating. As a result of isothermal annealing, Avrami exponents were found and mechanisms of crystallization were determined. Using continuous heating, the activation energy was found by the Kissinger method. В работе исследовались магнитомягкие аморфные сплавы системы Fe–Ni–P–B–Si–C. Была изучена кинетика кристаллизации сплавов с использованием термического анализа при режимах: изотермической выдержки и непрерывного нагрева. В результате проведения изотермического отжига были найдены показатели Аврами и определены механизмы кристаллизации. По методу Киссинджера при непрерывном нагреве определена энергия активация.

Abstract

The effect melt spinning, nitriding, and cerium doping have on the structural and magnetic hysteresis properties of alloys based on NdFe11Ti compound with ThMn12-type structure is studied at ambient temperature. It is established that the best combination of magnetic hysteresis properties is observed for (Nd1 – xCex)Fe11Ti alloys at x = 0.2 and 0.3 after melt spinning and nitriding. [ABSTRACT FROM AUTHOR]
