A Hall–Petch (H–P)-type dependence is demonstrated for reciprocal activation volume measurements nanocrystalline and conventional grain size, strengthened Ni Cu materials, consistent with predictions derived from the dislocation pile-up model. The observed H–P indicates that shear stress cross-slip must be involved in full size regime transmission of plastic flow at boundaries fcc metals.
The influence of grain size on creep rate in AISI type 316 stainless steel has been investigated at 873 and 973 K over a wide range applied stresses. Grain boundaries contribute to strengthening high stresses (180–260 MN m−2) but this does not correlate with the available models which attempt incorporate Hall–Petch effect into temperature strain equations. importance loading determining indicated. was generally constant increased small sizes lower attributed contribution boundary sliding...
Nitrogen-bearing types 304 and 316 stainless steels thermally aged at 823, 873 923 K for various durations were investigated to understand the relation between sensitized microstructure (intergranular corrosion) pitting corrosion resistance. The was assessed as per ASTM A262 practice A (electrolytic etch test) electrochemical potentiokinetic reactivation (EPR) tests; resistance evaluated in an acidic chloride medium by potentiodynamic anodic polarization method. results indicated that...
This paper presents the role of Dynamic strain ageing (DSA) on Low Cycle Fatigue (LCF) properties a type 304 stainless steel at 823K.Dynamic in low cycle fatigue is manifested as peak saturation stress, minimum plastic strain, an increase work hardening rate and times associated with serrated stress-strain hysteresis loops.Dynamic also increases inhomogeneity deformation during fatigue.Persistent slip bands are observed interior material intergranular cracking.
Epitaxial graphene/ferromagnetic metal (Gr/FM) heterostructures deposited onto heavy metals have been proposed for the realization of spintronic devices because their perpendicular magnetic anisotropy and sizable Dzyaloshinskii-Moriya interaction (DMI), allowing both enhanced thermal stability stabilization chiral spin textures. However, establishing routes toward this goal requires fundamental understanding microscopic origin unusual properties. Here, we elucidate nature induced spin-orbit...
