    • Abstract
  • Cyclic loading tests with variable strain amplitudes were conducted on 0Cr18Ni24Mo6N weld metal and cyclic stressstrain behavior was analyzed. The results indicated that elastic modulus and yield stress both decreases linearly with increasing strain amplitude. Linear relationship was found between true stress and true strain logarithm in plastic deformation region. True stress and true strain met the single logarithm constitutive model in cyclic plastic deformation region and the parameters of this model for 0Cr18Ni24Mo6N weld metal were determined.
