Process Parameters Study on Structure and Properties of Zr-Based Bulk Metallic Glasses

Abstract

The effects of different process parameters on the microstructure and mechanical properties of Zr-based bulk metallic glass were studied by using four factors and four levels of orthogonal experiment. Through the observation and analysis of the X-ray diffraction pattern, room temperature compressibility, microhardness distribution and transmission electron micrograph of the [Zr0.72-x(Cu0.59Ni0.41)0.28+x]88-yAl12+y (atomic percent) amorphous alloy with different process parameters, the results show that the compressive strength of the amorphous alloys with composition of [Zr0.73(Cu0.59Ni0.41)0.27]88Al12 and [Zr0.73(Cu0.59Ni0.41)0.27]87Al13 amorphous alloy under the corresponding processing parameters has reached 2411MPa and 1993MPa, and the plastic strain of the alloys is 33.8% and 19.3%. At the same time, through orthogonal analysis, in the four process parameters, the superheat temperature of the melt during the preparation of the alloy mainly affects the compressive strength of the alloy, while the cooling rate of the melt during the preparation of the alloy has a great influence on the plastic properties of the alloy.

Application of Fe-Based Amorphous Alloy in Industrial Wastewater Treatment: A Review

“…Secondly, the single-phase property of MGs is conducive to the uniform dispersion of reactants on its surface, forming a chemically homogeneous environment, and the high reaction activity is also attributed to the high concentration of unsaturated coordination atoms on the surface [9]. In addition, the element composition and atomic ratio of MGs can be widely adjusted according to the nature of pollutants and treatment environment [10]. Common MGs in the field of water treatment can be divided into the following categories: (1) The most widely used Fe-MGs [11].…”
