摘要: The plasticity behavior of the annealed HASTELLOY C-22HSTM alloy, a face-centered cubic (FCC), nickel-based superalloy, was examined by in-situ neutron-diffraction experiments at room temperature. Monotonic-tension and low-cycle-fatigue were conducted to observe plastic alloy. tension straining cyclic-loading deformation studied as function stress. behaviors during are discussed in light relationship between stress dislocation-density evolutions. calculated evolutions within alloys reflect strain hardening cyclic hardening/softening. Experimental lattice strains compared verify mechanism selected levels for loadings. Combining with calculations dislocation densities, give an evidence
