Notes:
Effect of Cr addition on damping capacity, mechanical property, and corrosion resistanceof Fe-18%Mn martensitic alloy has been studied. Martensite start temperature (Ms) of the alloydecreases linearly from 150 to 25[removed info] with increasing Cr content up to 15%. The damping capacitydecreases gradually from 27 to 23% in SDC with increasing Cr content from zero to 10%, anddecreases rapidly with further Cr content. The tensile strength of the alloy maintains a level of 60[removed info]/[removed info] regardless of Cr content with an elongation of 20 to 25%. Immersion test in 5% NaClsolution 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 mechanicalproperty and corrosion resistance of the alloy with a lesser decrease in damping capacity is about10%
