摘要：We reported the simulation and the analysis of the residual stress within the graded interlayered joints of MoSi2 to 316L stainless steel fabricated by spark plasma-sintering (SPS) technique. The residual stress in the joints was analyzed by the finite element ANSYS code. The results show that the maximum radial and axial residual tension stresses first decrease and then increase with the increase of the compositional distribution exponent (P), and consistently decrease with the increase of the number (n) and the thickness (d) of graded layer, respectively. The optimal values of compositional distribution exponent, the thickness, and the number of graded interlayered joints of the MoSi2 composite/316L are P = 0.8, d = 1.0 mm, and n = 9, respectively. The residual tension stresses in the samples treated by nine graded interlayers are reduced to 24% and 25% of those in the joints without the interlayer, respectively. ? 2008 ASM International.
