摘要

本研究通过在不同温度下进行静态淬火制备了 Zr62.5Cu18.5Fe5Al10Nb4 块状金属玻璃（BMGs）。结果表明，高淬火温度下制备的 Zr62.5Cu18.5Fe5Al10Nb4 BMGs 比低淬火温度下制备的 BMGs 具有更好的耐腐蚀性。高温淬火的 Zr62.5Cu18.5Fe5Al10Nb4 BMGs 结构为无定形，而低温淬火制备的样品则含有一些纳米晶体。研究了不同淬火温度下 Zr62.5Cu18.5Fe5Al10Nb4 BMGs 的耐腐蚀性与底层结构之间的相关性，并分析了其在氯化钠溶液中的腐蚀机理。

Controlling the static quenching temperature to improve the corrosion resistance performance of Zr-based bulk metallic glass

In this study, Zr_62.5Cu_18.5Fe₅Al₁₀Nb₄ bulk metallic glasses (BMGs) were prepared by static quenching at different temperatures. The results show that Zr_62.5Cu_18.5Fe₅Al₁₀Nb₄ BMGs prepared at high quenching temperature exhibit better corrosion resistance than those prepared at low quenching temperature. The structure of the Zr_62.5Cu_18.5Fe₅Al₁₀Nb₄ BMGs quenched at high temperature is amorphous, whereas the samples prepared at low quenching temperatures contain some nanocrystals. The correlation between the corrosion resistance and the underlying structure of the Zr_62.5Cu_18.5Fe₅Al₁₀Nb₄ BMGs at different quenching temperatures was studied, and the corrosion mechanism in a sodium chloride solution was analyzed.

期刊介绍： The Journal of Non-Crystalline Solids publishes review articles, research papers, and Letters to the Editor on amorphous and glassy materials, including inorganic, organic, polymeric, hybrid and metallic systems. Papers on partially glassy materials, such as glass-ceramics and glass-matrix composites, and papers involving the liquid state are also included in so far as the properties of the liquid are relevant for the formation of the solid. In all cases the papers must demonstrate both novelty and importance to the field, by way of significant advances in understanding or application of non-crystalline solids; in the case of Letters, a compelling case must also be made for expedited handling.
