Warm-forged Type 304L stainless steel specimens have been tested in high temperature hydrogenated water under slow strain rate tensile test conditions to investigate the effect of machining on stress corrosion crack initiation. Roughness, residual and cross-section microstructures as-machined surfaces were characterized prior tests, both plan-view examinations performed post-test. The results indicated that produced a deformation layer by an ultrafine-grained outer highly deformed inner...
The effect of machining on stress corrosion crack initiation annealed Type 316L stainless steel was investigated through accelerated testing in high-temperature hydrogenated water. It observed that cracks only initiated machined surfaces with marks perpendicular to the loading direction and a porous inner oxide layer identified as an important factor contributing initiation. Furthermore, most stopped within machining-induced near-surface ultrafine-grained residual stresses did not appear...
Surface machining is often assumed to be detrimental stress corrosion cracking (SCC) in nuclear power plant components because of localized deformation, high associated hardness, roughness and tensile residual stresses. However, the present work, SCC initiation studies for a warm-forged Type 304L stainless steel high-temperature water showed that ~1–2 μm thick ultrafine-grained layer introduced by improved resistance. Removing macroscopic ridges via grinding decreased but led more extensive...
The laser powder bed fused (LPBFed) stainless steels showed anomalous and localized corrosion behavior in the nuclear reactor high-temperature water compared to their wrought counterparts, which affects performance during plant operation. In this study, advanced microstructural characterization was performed on LPBFed 316 L sample along with after tests understand underlying mechanisms. results that an inhomogeneous/discontinuous inner oxide layer formed L, contrast continuous specimen. This...
Cold-worked Type 304L/316L stainless steel specimens, which contained different amounts of martensite (α′/ε), were tested in high-temperature hydrogenated water under slow strain rate tensile (SSRT) test conditions to understand the role on stress corrosion crack (SCC) initiation. These specimens characterized prior and after SSRT tests using complementary analytical techniques. It was observed that a higher necessary induce SCC initiation for cold-rolled 304L compared other cold-worked...
Corrosion mechanism of 316 L stainless steel produced by laser powder bed fusion-hot isostatic pressing (LPBF-HIP) and metallurgy-hot (PM-HIP) is studied with in-situ electrochemical impedance measurements coupled to detailed oxide film characterization. Quantitative analysis spectra using the Mixed-Conduction Model estimation local kinetic transport parameters interpretation in-depth elemental composition profiles indicated lower corrosion oxidation rates LPBF-HIP PM-HIP materials in...
The oxidation mechanisms of 316 L stainless steel in high-temperature hydrogenated water were investigated on machined and polished surfaces via complementary analytical techniques. differences microstructure the inner oxides shown to be responsible for fast surfaces. In fact, machining promoted formation a ∼2 μm thick ultrafine-grained layer which developed more porous fine-grained oxide than that formed surface. faster kinetics was attributed accelerated oxygen anions metal cations...
The effects of surface preparation and stress on oxidation carburization were investigated in a simulated AGR environment Type 316H stainless steel significantly influenced its behaviour. 600-grit ground samples formed thin chromia layer, while an OPS polish resulted thicker duplex oxide layer. Pre-straining or plastic deformation at high temperatures disrupted the film, leading to transition. Enhanced hardening associated with was observed only polished surfaces subjected creep because...
Mechanical properties of monolithic metal–organic frameworks (MOFs), especially static and time-dependent plasticity, are essential to the mechanical stability their device applications. In this study, hardness elastic moduli monoZIF-8 monoUiO-66 MOFs were compared analyzed in terms formation enthalpy, topological structure, crystal defects formed during sol–gel synthesis. For first time, creep behaviors investigated using nanoindentation. The stress exponent n values for calculated be about...
