Comparative experiment of steel bar corrosion at concrete construction joints
Frontiers in Materials, 2022 Introduction: Construction joint is common and even inevitable in most of the reinforcement concrete structures. This study was to assess the effect of construction joints on chloride-induced corrosion of reinforcing steel in concrete.Methods: Test ...

Exploiting Residual Elements Arising from Scrap Steel in Future Sustainable Steel Alloy Design
steel research international, EarlyView.Herein, the effects of residual elements Cu and Sn on grain growth, recrystallization, and phase transformation in C–Mn steel are summarized, and a case study is presented on how the presence of residual elements can be exploited to reduce deliberate Nb microalloying while achieving the same grain size control and strength during thermomechanical ...

Predicting the Ms temperature of lean alloyed ferritic–austenitic stainless steels
Journal of Materials Research and TechnologyA set of laboratory hot-rolled and thermally cycled 19–22 wt% Cr lean alloyed ferritic–austenitic stainless steels were studied with respect to calculated equilibrium austenite composition and experimental martensite start (Ms) temperature.

steel research international, EarlyView.Heat treatments that alter the proportions of austenite and ferrite phases or induce the precipitation of phases such as sigma in duplex stainless steel UNS S32205 make it more susceptible to pitting and crevice corrosion. However, the effects of these treatments are not always evident when analyzed using the cyclic polarization technique.

Micro-scale strain distribution in hot-worked duplex stainless steel [PDF]
, 2005 A modified microgrid technique has been applied to a laboratory-made duplex stainless steel, to experimentally simulate the local state of deformation of the austenite-ferrite microstructure of low-alloy steels subject to intercritical deformation.

steel research international, EarlyView.Laser welding of duplex stainless steel disrupts phase balance, promotes nitride precipitation, and reduces fatigue resistance. Postweld heat treatment restores austenite and dissolves nitrides, but the resulting crystallography and phase morphology still impair fatigue performance.

Performance enhancement of the photovoltaic cells system by using the pneumatic routers [PDF]
, 2021 Solar photovoltaic modules are of immense benefits to ordinary people in terms of independent energy solutions and conventional fuel savings. However, due to the inherent drawback of lower efficiencies per unit area, these technologies adoption rates

Austenitic-ferritic stainless steel containing niobium [PDF]
Rem: Revista Escola de Minas, 2013 The austenitic-ferritic stainless steels present a better combination of mechanical properties and stress corrosion resistance than the ferritic or austenitic ones. The microstructures of these steels depend on the chemical compositions and heat treatments.

steel research international, EarlyView.Prebending of 304L/Q345R cladded plates significantly alters the subsequent weld thermal cycle and modifies the local interfacial microstructure. Combined electron backscatter diffraction (EBSD) and microscopy analysis demonstrates that deformation twinning, martensitic transformation, and defect initiation are concentrated at the trimaterial junction,
