To solve the traditional aluminum alloy die-casting defects, electrically-assisted (EA) die-casting is regarded as a potential method to improve the microstructure of traditional casting. The electromagnetic and electrothermal effects during EA solidification of pure aluminum are investigated through numerical simulation and experiment by loading varied current density, duty ratio, and frequency. The results show that the mechanical strength of pure aluminum using EA solidification increased by 64.6 % compared with the traditional method, which is attributed to the improved equiaxiality and refinement of grains. As the current density increases, the material strength initially rises to the peak at the current density of 2.27 A/mm² and then begins to decline. Besides, the material strength increases with an increase in current frequency and decreases with an increase in duty ratio. The above phenomena are attributed to the competitive action of electromagnetic and electrothermal effects. On the one hand, the current-induced Lorentz force and electromagnetic oscillations cause shear effects on the pure aluminum particles, inhibiting the grain coarsening and refining the grains. However, the current-induced Joule heating (electrothermal effect) can promote grain growth, which is opposite to the electromagnetic effect. The opposite action of electromagnetic and electrothermal effects leads to the material strength first increasing and then decreasing with increased current density. The findings provide a theoretical basis for optimizing EA solidification processes, enabling improvements in mechanical properties and expanding applications in lightweight automotive.</div></div>","PeriodicalId":367,"journal":{"name":"Journal of Materials Processing Technology","volume":"339 ","pages":"Article 118827"},"PeriodicalIF":6.7,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143725322","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}

However, the effect of applied pressure, which is considered the most influential factor, on the thermo-mechanical behaviours and macro-/microstructural evolution at the interface during PJFW of carbon steel has not been studied in depth, leading to a poor understanding of the fundamental interface joining mechanism. In the present study, PJFW was performed on a high-carbon steel with varying pressure conditions where the behaviours in thermal, mechanical, and metallurgical were carefully investigated via experimental and numerical approaches. The results show that applied pressure uniquely determined the peak temperature according to temperature-dependent strength variation of base metal. High-carbon-steel rods were thus well joined by PJFW at uniform temperatures lower than A₁ point, which effectively prevented the brittle martensitization, while also avoided the uneven temperature issue in rotary friction welding. Appropriate thermo-mechanical condition not only provided high enough pressure to sufficiently fragment oxides, but also high enough temperature to facilitate grain boundary migration to eliminate micro-defects. Simulations confirmed that increased interfacial strain helped further disperse oxides, produce more metal fresh surfaces and promote their atomic-scale adhesion, thereby suppressing the formation of unbonded regions and voids. The clarified interface joining mechanism regarding defect closure correlated with mechanical-induced oxide fragmentation and thermal-driven grain boundary migration would provide an inspiring perspective to the community of solid-state pressure welding.</div></div>","PeriodicalId":367,"journal":{"name":"Journal of Materials Processing Technology","volume":"339 ","pages":"Article 118824"},"PeriodicalIF":6.7,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143725286","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}

The gap tolerance and hump defect suppression across the entire weld of thick-plate steel were investigated, and the associated mechanisms were elucidated.

In light of the current lack of sufficient research, the effects of blue and hybrid laser welding were clarified, and the mechanisms behind the observed phenomenons were analyzed in this study. The research found that near-infrared (NIR) laser welding caused porosity defects due to keyhole collapse and turbulent molten pools.

Whether the printed device efficiency depends on printing conditions is unclear. Our study shows that there exist clogging and terminated critical pulling speeds in meniscus-guided 3D printing with material supplied by the evaporation-induced capillary replenishment flow, where only the pulling speed is within this range 3D printing could be successfully implemented. The printable ink viscosity can be higher than the previously reported if the pulling speed criterion is satisfied.

A more comprehensive formulation than the literature reported ones describing the dependence of the 3D-printed micropillar diameter on the micropipette pulling velocity and diameter is derived, which agrees well with the experimentally printed micropillar diameters under different conditions and indicates that 3D-printed micropillar diameter adjustment is governed by the meniscus shape and its evaporation rate. Based on the improved 3D-printed structure adjustment technology, the 3D microbridge humidity sensors and 3D micropillar capacitor electrodes can be fabricated with high repeatability and efficiency. The 3D-printed microscale devices’ efficiencies in this study are superior to most previously reported microscale devices, with their efficiencies adjustable by the relative humidity during the printing process.

However, it often results in coarse grain structures and considerable residual stress, ultimately deteriorating mechanical properties and fatigue life of remanufactured components. This study addresses this issue by utilizing a customized in-situ hot rolling-assisted WAAM (HR-WAAM) system, specially designed for rotational components, to remanufacture a motor shaft using a high-strength low-alloy steel wire. The rolling temperature was maintained within the ferrite phase region. Comparative analyses of single-layer, double-layer, and multi-layer samples were conducted to uncover the combined effects of in-situ hot rolling and thermal cycling on microstructure and mechanical properties. In-situ hot rolling introduces substantial low-angle grain boundaries and dislocations, serving as nucleation sites for recrystallization. Thermal cycling during subsequent deposition not only provides necessary activation energy to enhance grain boundary mobility and thus promotes recrystallization, but also induces various solid-state phase transformations to facilitate grain refinement and microstructural homogenization. An optimal processing window was identified with a rolling temperature of 600–700 °C and 23 % rolling strain. The yield strength of HR-WAAM low-alloy steel increased from 604 MPa to 786 MPa while maintaining an elongation of 20 %, comparable to that of WAAM samples. Moreover, the high-cycle fatigue strength substantially increases from 428 MPa to 501 MPa.

Unlike other existing methods relying on external assistance, this study introduces a novel material design strategy to intrinsically improve the machinability of titanium alloys and Ti-MMCs by incorporating networked graphene nanosheets (GNSs) as internal reinforcement. To systematically evaluate this approach, three Ti-6Al-4V (Ti64) alloy-based materials: the matrix alloy, a composite reinforced with randomly dispersed GNSs (GNSs/Ti64 composite), and a composite reinforced with a networked GNSs structure (networked GNSs/Ti64 composite), were respectively designed and employed as workpiece in ultra-precision micro-cutting tests. The results reveal that the networked GNSs/Ti64 composite exhibits significantly reduced machining vibration induced by machining force, enhanced surface integrity, and more uniform chip formation compared to both the Ti64 alloy and GNSs/Ti64 composite. In-depth material characterization and mechanistic analysis attribute this improvement to the networked GNSs structure that optimizes the occurrence of shear fracture in the primary shear zone, leading to more uniform serrated chips for chip formation.
