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}

In addition, we examined its effect on strength and ductility. The (α+α′) duplex microstructure (for the as-solution treated and quenched specimens) demonstrates a strength-ductility balance that is at par or better than that of the equilibrium (α+β) bimodal structure (for 700 °C aged specimen). The strength of the (α+α') duplex microstructure that was aged at 500 °C for 1 h was significantly increased while retaining good ductility. Here, although no apparent structural changes in both nano- and micro scale level were observed in the primary α grains, three unique phase decomposition/structural evolutions in nano scale level that formed new domains distinguished into the Area 1, 2, 3 were observed in the fine acicular α' martensite region as follows. 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).
