Abstract

The Vickers hardnesses of 21 as-cast Ni-Ru-Zr alloys of different compositions were studied, and nanohardness indentations were done on the individual phases. The results were used to explain the brittleness by assessing the proportions of the phases, and their morphologies. The compound hardnesses varied between 704 - 1289 HV, with ~ZrRu2 being the hardest phase, and ~Zr2Ni7 being the least hard phase. The sample hardnesses were 300 - 1015 HV. Most of the samples were brittle, although there were regions of toughness around Ni36:Ru13:Zr51 and Ni20:Ru5:Zr75 (at.%). No alloy was identified to have potential good mechanical properties.

铸态Ni-Ru-Zr合金的硬度特性

研究了21种不同成分的铸态Ni-Ru-Zr合金的维氏硬度，并对各相进行了纳米硬度压痕分析。结果被用来通过评估相的比例和它们的形态来解释脆性。复合硬度在704 ~ 1289 HV之间变化，其中~ZrRu2相硬度最高，~Zr2Ni7相硬度最低。样品硬度为300 ~ 1015hv。Ni36:Ru13:Zr51和Ni20:Ru5:Zr75 (at.%)附近有韧性区，但大部分样品呈脆性。没有发现有潜在良好力学性能的合金。

期刊介绍： University of Belgrade, Technical Faculty in Bor, has been publishing the journal called Journal of Mining and Metallurgy since 1965 and in 1997 it was divided in two independent journals dealing with mining and metallurgy separately. Since 2009 Journal of Mining and Metallurgy, Section B: Metallurgy has been accepted in Science Citation Index Expanded. Journal of Mining and Metallurgy, Section B: Metallurgy presents an international medium for the publication of contributions on original research which reflect the new progresses in theory and practice of metallurgy. The Journal covers the latest research in all aspects of metallurgy including hydrometallurgy, pyrometallurgy, electrometallurgy, transport phenomena, process control, solidification, mechanical working, solid state reactions, materials processing, surface treatment and relationships among processing, structure, and properties of materials.
