摘要

Effects of inclusions on ductile fracture have been examined with a series of laboratory produced Fe-42 pct Ni alloys containing diffeent amounts of S, Mn and O. The inclusion volume fraction was varied between approaximately 0.01 and 3.00 pct. Axisymmetric tensile bars and cylindrical, double shear test samples were tested in the recrystallized condition. In the tensile test, increasing inclusion volume fraction significantly reduced post-uniform elongation and strain to fracture #epsilon#_f. In the shear test, fracture displacement obtained from load displacement data and strain to fracture calculated from the shear test samles decreased with increasing inclusion volume fraction. Appliicability of different models is considered.
