Hardness characteristics of as-cast Ni-Ru-Zr alloys
Abstract
<jats:p>The Vickers hardnesses of 21 as-cast Ni-Ru-Zr alloys of differentcompositions were studied, and nanohardness indentations were done on theindividual phases. The results were used to explain the brittleness byassessing the proportions of the phases, and their morphologies. Thecompound hardnesses varied between 704 - 1289 HV, with ~ZrRu2 being thehardest phase, and ~Zr2Ni7 being the least hard phase. The sample hardnesseswere 300 - 1015 HV. Most of the samples were brittle, although there wereregions of toughness around Ni36:Ru13:Zr51 and Ni20:Ru5:Zr75 (at.%). Noalloy was identified to have potential good mechanical properties.</jats:p>
