Abstract

Effect of Cr addition on damping capacity, mechanical property, and conosion resistance of Fe-18%Mn martensitic alloy has been studied. Maitensite start temperature (Ms) of the alloy decreases linearly from 150 to 25t°C with increasing Cr content up to 15%. The damping capacity decreases gradually from 27 to 23% in SDC with increasing Cr content from zero to 10%, and decreases rapidly with further Cr content. The tensile strength of the alloy maintains a level of 60 kg/mm2 regardless of Cr content with an elongation of 20 to 25%. Immersion test in 5% NaCl solution leads to the result that the corrosion resistance of the alloy becomes excellent above 10% Cr. From the above results, it is concluded that the optimum Cr content to improve the mechanical property and corrosion resistance of the alloy with a lesser decrease in damping capacity is about 10%.
