Abstract

The structural changes in the Zr₆₂Cu₂₂Fe₅Al₁₀Ce₁, Zr₆₂Cu₂₂Fe₅Al₁₀Nd₁, Mg₅₇Cu₃₁Y_6.6Nd_5.4 and Pd_42.5Cu₃₀Ni_7.5P₂₀ bulk metallic glasses tested upon scratch tests with an atomic force microscope equipped with a diamond-tip cantilever at a load varied from 1 to 6 μN were verified by using transmission electron microscopy. The Mg₅₇Cu₃₁Y_6.6Nd_5.4 BMG demonstrated a unique behavior under the wear conditions related to deformation hardening. Wear resistance and scratch resistance both increase with load for this alloy, indicating local structural ordering and nanocrystallization under mechanical deformation, unlike other BMGs.

大块金属玻璃刮擦磨损的剪切诱导纳米晶化

采用带金刚石尖悬臂的原子力显微镜对Zr62Cu22Fe5Al10Ce1、Zr62Cu22Fe5Al10Nd1、Mg57Cu31Y6.6Nd5.4和Pd42.5Cu30Ni7.5P20块体金属玻璃在1 ~ 6 μN载荷作用下的结构变化进行了透射电镜验证。Mg57Cu31Y6.6Nd5.4 BMG在与变形硬化相关的磨损条件下表现出独特的性能。与其他bmg合金不同，该合金的耐磨性和抗划伤性随载荷的增加而增加，表明在机械变形下局部组织有序和纳米晶化。

期刊介绍： Wear journal is dedicated to the advancement of basic and applied knowledge concerning the nature of wear of materials. Broadly, topics of interest range from development of fundamental understanding of the mechanisms of wear to innovative solutions to practical engineering problems. Authors of experimental studies are expected to comment on the repeatability of the data, and whenever possible, conduct multiple measurements under similar testing conditions. Further, Wear embraces the highest standards of professional ethics, and the detection of matching content, either in written or graphical form, from other publications by the current authors or by others, may result in rejection.
