Optimizing this process requires the design and integration of discrete forming stages to establish an optimized manufacturing plan. This paper presents a multistage deep drawing recommendation system that combines a novel forming quality evaluation function, called the Integrated Multistage Deep Drawing Evaluation Function (IMSDDEF), with the Non-dominated Sorting Genetic Algorithm III (NSGA-III). The system aims to suggest near-optimal forming plans with a minimal number of forming stages, while accounting for blank material properties, target-net shape, product quality, and the intermediate failures. Artificial Neural Network surrogate models for classification and regression have been developed, trained on finite element simulation data with plastic anisotropy to predict product formability, minimum height, and thickness based on design variables at each forming stage. Flowchart-based decision-making logic in IMSDDEF integrates these surrogate models to determine key performance metrics, including the appropriate number of forming stages, as well as the product's shape loss and minimum thickness. IMSDDEF coordinates with NSGA-III to derive Pareto-optimal solutions within a minute, enabling trade-offs between conflicting objectives. From the resulting Pareto front, the most suitable forming plan is selected through detailed comparative analysis. Experimental validation is conducted to confirm the reliability and effectiveness of the proposed system. The novel function IMSDDEF could be further generalized to other sequential material processing optimization scenarios to optimize manufacturing plans beyond multistage deep drawing.</div></div>","PeriodicalId":367,"journal":{"name":"Journal of Materials Processing Technology","volume":"341 ","pages":"Article 118881"},"PeriodicalIF":6.7,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143927951","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 results indicated that the effectiveness of the feeding strip depended on its composition and melting point. The 316 L strip with a higher melting point did not melt completely. Feeding 654SMO strip slightly improved the dendritic structure, while feeding 904 L strip significantly expanded the equiaxed zone, refined the dendrites, reduced central Mo segregation, and inhibited σ-phase precipitation. The following mechanisms were revealed. The melting strip produced floating dendrites that acted as nucleation particles. The 654SMO strip and floating dendrites melted quickly, offering a limited refining effect on the dendritic structure. By contrast, the higher melting-point 904 L strip exhibited a longer melting time, and the 904 L floating dendrites survived and proliferated better, thereby markedly improving the dendritic structure. Moreover, feeding the 904 L strip resulted in stronger abilities to inhibit the columnar grain growth and Mo-rich interface movement, discretize and refine Mo segregation regions, and shorten the solidification time. Moreover, the 904 L strip with lower Mo content (4.38 wt%) diluted the central Mo content. All these roles significantly reduced central Mo segregation.

Mechanistic analysis indicates that sintering at 910°C allows nickel to suppress copper-sulfur interfacial embrittlement while promoting titanium carbide (TiC) bonding reinforcement. This process achieves an optimal flexural strength of 72.63 MPa with 5 % PMMA-induced interconnected porosity.

Comparative grinding trials demonstrate transformative performance: surface roughness decreases by 30.45 % as porous channels retain grinding debris, thereby suppressing three-body abrasion.

The higher overall heat input in multi-pass GTAW and lower solubility of strengthening elements in completely austenitic weld metal deteriorated the mechanical properties of joints. The eutectic high-entropy alloy interlayer imparted a high-entropy effect to the weld metal, resulting in increased mixing entropy and sluggish diffusion behavior. This led to better mixing of the weld metal and a functionally graded structure with minimized unmixed zones, lower carbon migration and reduced peak hardness at the weld metal interface. The flux-assisted arc constriction and reversal of the Marangoni convection effect in activated flux GTAW enabled deeper penetration with lower heat input in two passes compared to the traditional approach. The increased cobalt content (1.36 wt%) in the weld metal suppressed the delta ferrite formation and imparted grain refinement by promoting secondary phase precipitation at the grain boundaries and strengthening the weld metal. The lower heat input in activated flux GTAW with higher nickel and cobalt content in eutectic high entropy alloy interlayer tailored a refined dual phase austenitic-martensitic microstructure with finer discrete secondary phases in weld metal resulting in superior mechanical properties compared to the traditionally welded joints in as-welded state.

Hence, this study successfully fabricated Al-Cu alloy wire with varying TiC content (0.6, 1.2, 2.0 wt%) using an in-situ molten salt reaction method and systematically investigated its enhancement mechanisms on WAAM Al-Cu alloy. The results reveal that TiC addition significantly refines the grain structure, reduces porosity, and enhances mechanical properties.

Mechanistic analysis reveals that the grain refinement was primarily attributed to enhanced heterogeneous nucleation and the effective inhibition of grain boundary migration. The strengthening mechanisms were dominated by three dominant mechanisms: (i) grain refinement strengthening via the Hall-Petch effect induced by TiC particles, (ii) Orowan strengthening resulting from the dispersion of rigid TiC particles within the matrix, and (iii) Load-bearing strengthening enabled by robust interfacial bonding between TiC particles and the matrix. Furthermore, the improvement in ductility was mainly attributed to porosity reduction, a full columnar-to-equiaxed transition (CET), refined grain structures, and the formation of uniformly distributed fine precipitates.
