Topside fracture readily occurs during this process, increasing the risk of chip failure. However, there is currently no research on the mechanism of topside fracture formation and control methods specifically for dicing. To address this challenge, this study investigates the formation mechanism of topside fracture during silicon wafer dicing. The dicing blade is divided into two grinding zones based on material removal: the primary grinding zone (PGZ) on the outer circumference, which performs plunge grinding, and the secondary grinding zone (SGZ) on the side of the blade, which performs face griding. Topside fracture is classified into three types—the primary grinding zone, the secondary grinding zone, and mixed fracture—based on the interaction between these zones. The formation processes of these fracture types are discussed in detail. A topside fracture area model, which accounts for blade characteristics, was developed by integrating the three fracture formation mechanisms with crack propagation conditions, addressing the theoretical gap in the study of fracture during the dicing of brittle materials. Subsequently, a series of silicon dicing parameter experiments were conducted, accurately identifying the three types of fracture. It was found that the proportion of secondary grinding zone fracture was inversely proportional to the average fracture area. Therefore, by referring to the model and controlling the processing parameters, it is possible to reduce the proportion of secondary grinding zone fracture and, in turn, control the fracture area. Additionally, the segmented model established in this study, which takes different types of fracture into consideration, reduced the average error rate of fracture area calculations from 19.5 % to 12.51 %, compared to a model that does not account for fracture types. This research provides valuable insights into reducing silicon dicing fracture areas and improving dicing quality, serving as a reference for the study of fracture in the dicing of other hard-brittle materials.</div></div>","PeriodicalId":367,"journal":{"name":"Journal of Materials Processing Technology","volume":"342 ","pages":"Article 118937"},"PeriodicalIF":6.7,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144291013","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study reveals the influence of interface contact characteristics on nugget evolution and mechanical properties by controlling electrode surface conditions (adhesion/pitting degree), and proposes an electrode optimization strategy based on curvature radius matching. The results show that when 83 % of the electrode end face is adhered without pitting, the increased contact resistance reduces heat dissipation, expands the nugget diameter, and improves the tensile shear properties by 6.3 %. However, this condition decreases welding stability and induces recrystallization of the nugget equiaxed crystals, reducing crystalline defects. When the pitting area is less than 26 %, no significant effect on mechanical properties is observed; when the pitting area exceeds 55 %, the nugget size decreases by 6.7 %, and the tensile shear properties decline by 21 %. To address pitting issues, a combined scheme of an upper electrode with a large curvature radius and a lower electrode with a small curvature radius is proposed. Experimental and simulation validations show that the upper electrode delays pitting by increasing the contact area to uniform current distribution, enhancing electrode life by 2.5 times; the lower electrode (R80) utilizes a small curvature radius to concentrate heat generation, increasing the nugget size by 6.1 % and improving tensile shear properties by 6.4 %. Additionally, this study first discovers that current aggregation at the nugget edge during welding leads to a ring-shaped pitting phenomenon, which shifts outward as the nugget expands.

This work reports a fundamental process advancement: the liquid-induced healing (LIH) technique uniquely integrates buoyancy-driven gas expulsion with controlled grain coarsening to simultaneously eliminate defects and enhance high-temperature performance in laser beam powder bed fusion components. Using laser beam powder bed fusion fabricated IN718 as the demonstration alloy, we systematically evaluate the defect healing mechanism and its effects on microstructure and mechanical properties. The results show that LIH increases the relative density from 97.99 % to 99.97 % and improves tensile elongation at 650°C by 1.8 times, with only an approximate 10 % reduction in material strength. Notably, the fatigue performance (25°C, σ_max = 950 MPa) demonstrates a 3.4 times extended lifetime. More importantly, the creep life (650°C, 650 MPa) increases by 6.5 times owing to the simultaneous defect healing and microstructure regulation.

To address this need, here we report a combined experimental and computational study to investigate the effects of groove gap and ring-core ratio on molten pool morphology in ring-core adjustable laser welding with a narrow gap structure (NGR-CALW). The molten pool flow behavior and temperature gradient distribution under varying groove gaps and ring-core ratios were thoroughly analyzed through numerical flow field simulations, elucidating the evolution mechanisms of weld morphology and microstructural characteristics. The results demonstrate that an increased groove gap enables a transition in the weld cross-sectional shape from narrow and deep to wide and shallow. Moreover, an increase in the ring-core ratio significantly widens the effective sidewall melting area, resulting in a more rounded and fuller upper weld profile. The morphological diversity of molten pool stems from differential heat dissipation dynamics and cooling gradients, consequently inducing spatially heterogeneous microstructures between concave-shaped, flat-shaped and convex-shaped molten pools. Finally, NGR-CALW with optimizing groove gap and ring-core ratio matching was found to favor rapid solidification and the development of finer solidification microstructure in joining 22 mm thick TC4 titanium alloys.

The results demonstrated that as the strain rate increased from 0.001 s⁻¹ to 2310 s⁻¹, the elongation increased significantly by 27 %. The underlying mechanisms governing the strain rate dependence of plasticity were elucidated through microstructural analysis. The frequency of deformation twinning increased notably with strain rate. This effect was especially obvious during the transition from LSR to HSR. Deformation twinning inhibited dislocation motion and enhanced the work hardening capacity. Simultaneously, hard oriented grains (HOG) were found to play a significant role in the plastic deformation under HSR loading, enhancing the deformation coordination between grains and improving material deformation uniformity. This improvement in deformation uniformity mitigated premature localized strain and necking.
