Исследование влияния углерода на механические свойства композиционного сплава на основе вольфрама, полученного методом электроискрового спекания

Abstract

In this work the effect of carbon content in tungsten alloy supported with martensiteageing dope is investigated. The alloy was obtained by spark plasma sintering (SPS) method and its composition was: 85% wt. W, 15% martensite-ageing dope. This composition was doped with 0,1 or 0,3% wt. of carbon component. Increase of carbon content up to 0,1% wt. resulted in durability and plasticity growth though further increase of carbon content up to 0,3% wt. resulted in growth of durability, but decrease of plasticity.
