This study primarily utilizes grain refinement to regulate the micro-nano structure, aiming to achieve an optimal balance between mechanical performance and residual stress mitigation. The results demonstrate that grain refinement significantly reduces residual stress. Compared to the non-refined A356 alloy which exhibited high residual stress after solution treatment, the addition of 0.5 % Al-Ti-B reduced the residual stress by 73 MPa. Furthermore, after various aging durations, the residual stress of the A356 alloy with 0.5 % Al-Ti-B addition was consistently lower compared to the alloy without such addition. The grain-refined A356 alloy also maintained excellent mechanical properties, achieving a tensile strength of 282 MPa and an elongation of 8.9 %. TEM analysis revealed that thermal aging prompted the precipitation of numerous Mg₂Si phases in the A356 matrix, significantly reducing dislocation density and lattice distortion. Grain refinement decreased dislocation density at grain boundaries and promoted a finer, more dispersed distribution of precipitates, which reduced uneven thermal expansion and alleviated stress concentration. Thus, grain refinement not only markedly reduces residual stress but also preserves outstanding mechanical properties.</div></div>","PeriodicalId":54332,"journal":{"name":"Journal of Materials Research and Technology-Jmr&t","volume":"39 ","pages":"Pages 1017-1027"},"PeriodicalIF":6.6,"publicationDate":"2025-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145120868","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}

Experimental results indicate that 600 °C/400 MPa represents the optimal LTHP SPS condition for preparing dense core-shell structured Ti bulk without excessive grain growth. This inhibition of grain growth is attributed to the distinct densification behavior of LTHP SPS compared with conventional SPS method. Specifically, under conventional SPS, densification primarily occurs during the heating and holding stages, with plastic flow involved in initial heating stage transitioning to atomic diffusion driven by high temperatures dominating the subsequent sintering process. In contrast, LTHP SPS exerts a more pronounced effect on densification during the heating stage, where plastic flow is the dominant mechanism, accompanied by limited atomic diffusion due to lower temperatures. Entering the holding stage, plastic flow, atomic diffusion, and atomic migration all contribute to mild densification. Cooling predominantly involves atomic oscillations.

Through integrated analysis of thermodynamic simulations and non-isothermal kinetic experiments, the reduction behavior, phase reconstruction, and decomposition of MoSi₂ during the synergistic smelting process were systematically investigated. The magnetite phase and fayalite phase gradually decomposed under the influence of CaO and MoSi₂, following the reaction pathways: Fe₃O₄→FeO→Fe and Fe₂SiO₄→Fe_1.5Ca_0.5(SiO₃)₂→Fe. At approximately 950–1100 °C, an exothermic reaction occurred between MoSi₂ and copper slag, initiating in-situ formation of Fe₃Mo. CaO improved the thermodynamic conditions and facilitated reaction progression. After system melting, solid-liquid reactions further decomposed MoSi₂, while Mo and Si diffused into the slag, and Fe selectively captured Mo for directional enrichment. Differential scanning calorimetry analysis determined the activation energy for MoSi₂-driven copper slag reduction to be 113.470 kJ/mol, confirming MoSi₂ as an efficient reductant.

The coarse-grained alloys demonstrated a significantly lower corrosion rate than fine-grained alloys at 500 h corrosion, while the corrosion rate difference diminished when corrosion time was extended to 3000 h.

A corrosion multi-layer was confirmed, and NiO and Cr₂O₃ were found as the principal oxides.

This approach enhances efficient nanofluid penetration and lubrication at the micro-textured Si₃N₄ tool-chip interface. Initially, numerical simulations were conducted to analyze the flow and heat transfer characteristics of nanofluids in micro-textured channels under self-excited electric fields. A comprehensive electroosmotic flow and heat transfer model was established based on principles of electrostatics, thermodynamics, and fluid dynamics. The results demonstrated that increased electric field intensity enhanced both the electroosmotic force and flow velocity of nanofluids within micro-textured channels.
