This study aims to provide a comprehensive understanding about the effect of microstructural refinement on aqueous corrosion behaviour of NSB while keeping the bainitic volume fraction constant. Two different austenitization temperatures (900 °C and 1000 °C) followed by austempering at 250 °C resulted in different prior austenite grain size (PAGS) which led to correspondingly different bainitic lath thickness. The specimens were subjected to immersion test in 3.5 wt% NaCl solution for 10, 20, 30, 40 and 50 days. Specimen having finer bainitic lath thickness displayed lower corrosion rate and weight loss due to immersion. Cross sectional imaging using scanning electron microscope (SEM) revealed shallower penetration of electrolyte in case of finer bainitic lath specimen resulting in formation of a compact, uniform and adhered corrosion layer in comparison to a loose and non-uniform layer observed for coarser bainitic lath specimen. Raman spectroscopy and x-ray photoelectron spectroscopy (XPS) revealed oxyhydroxides to be present in larger proportions in specimens subjected to immersion for 10 days while specimens subjected to immersion for 30 days had higher proportions of oxides as compared to oxyhydroxides. Further immersion up to 50 days resulted in higher proportions of oxyhydroxides in case of both heat treated specimens. Electrochemical tests such as electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization (PDP) conducted on specimens immersed for 30 days showed that finer bainitic lath specimen displays higher corrosion resistance despite having thinner corrosion layer owing to its high compactness.</div></div>","PeriodicalId":47623,"journal":{"name":"Materialia","volume":"39 ","pages":"Article 102354"},"PeriodicalIF":3.0,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143313223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address these questions, the present study investigates some mechanical properties and the deformation response of a phase-separated soda-lime-silica glass with varying microstructures ranging from nanosized, interconnected to larger, dilute droplet structures. By maintaining a constant chemical composition, the direct influence of the microstructure morphology on certain mechanical properties is probed. Electron microscope images of crack tips reveal that the secondary phase can deflect and bridge propagating cracks in both interconnected and droplet microstructures, which is further confirmed by peridynamic simulations. Raman spectra show characteristic peak shifts of both amorphous silica and soda-lime glass during deformation, indicating a combined contribution of matrix and secondary phase. Notably, the interconnected structures exhibit smaller deformation zones, and cracks generated by low force indentations are significantly shorter compared to the droplet structures. These observed nanostructural effects lead to a 20 % increase in indentation fracture toughness and up to 40 % increase in flexural strength in interconnected structures. The increase in strength and toughness appears to be mainly related to the ability of certain morphologies to absorb stresses through densification of the secondary phase and to decrease the opening force of propagating cracks through crack deflection on interfaces.</div></div>","PeriodicalId":47623,"journal":{"name":"Materialia","volume":"39 ","pages":"Article 102349"},"PeriodicalIF":3.0,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143173284","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Under aging at 500 °C, fine acicular α′ martensite evolves into ultrafine globular α′ grains via enhanced recrystallization (corresponding to Area 1), followed by occurrences of β precipitation without elemental diffusional partitioning (corresponding to Area 2) and substitution from globular α' grains to ultrafine β subgrains (correponding to Area 3).
