It is often used to prepare high-strength ductile cast iron. In this paper, the effects of adding different contents of Ni on the microstructure and properties of ductile cast iron were investigated. The results showed that with the increase of Ni content from 3 to 9 wt.%, the density and the nodularity of ductile cast iron samples showed an upward trend, and the mean size of graphite decreased. The ductile cast iron containing 7 wt.% Ni exhibited the best mechanical properties, with ultimate tensile strength, yield strength, elongation, and Rockwell hardness were 1030 MPa, 772 MPa, 2.1%, and 40.5 HRC, respectively.

However, its pronounced work-hardening behavior during machining significantly affects surface integrity. Therefore, accurate prediction of surface microhardness is essential for component performance and tool life. Existing methods for rapid and reliable microhardness prediction remain limited. To address this gap, a data-driven prediction approach was proposed. First, a finite element (FE) model for milling GH4169 superalloy was developed using ABAQUS to simulate the effects of varying milling parameters. The residual strain on the machined surface was extracted from the simulation results and quantitatively correlated with Vickers microhardness, yielding a predictive model that was experimentally validated with all relative errors (REs) below 6%. Then, based on the data generated from this model, a particle swarm optimization (PSO)-optimized backpropagation neural network (BP-NN) model was constructed, with cutting speed, feed per tooth, and axial depth of cut as inputs and Vickers microhardness as the output. Comparative evaluation showed that the PSO-BP-NN model significantly outperformed the BP-NN model, achieving a 9.9% increase in R<sup>2</sup> and a 135.2% improvement in the ratio of performance to deviation (RPD), while reducing mean squared error (MSE) by 65.9% and mean absolute error (MAE) by 39.1%. Furthermore, the model accurately predicted surface microhardness under 12 additional independent milling parameter sets, with all REs below 11%, confirming its strong generalization capability for industrial applications.</p></div>","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"35 41","pages":"42663 - 42676"},"PeriodicalIF":2.6,"publicationDate":"2026-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149338577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Wire arc additive manufacturing (WAAM) has emerged as a promising approach for joining dissimilar metals by enabling controlled heat input, compositional grading, and layer-by-layer fabrication. In the present study, a multilayer deposition strategy was employed to join AISI 304 stainless steel to pure copper using WAAM through a cold metal transfer (CMT) mode. Detailed microstructural characterization using optical microscopy, scanning electron microscopy, and electron backscatter diffraction revealed the formation of a defect-free joint facilitated by a diffusion-driven bonding, exhibiting gradual compositional transition from coarse columnar SS304 grains to comparatively fine equiaxed Cu grains across the interface. Significant grain evolution without any preferred crystallographic orientation was observed on the Cu side, with greater diffusion depth of SS304 into Cu. Microhardness mapping indicated that the interfacial properties were governed by the harder SS304 phase. The hardness values across the interface varied between 109 and 187 HV, indicating a gradual transition from the softer Cu region to the stronger SS304 side. The SS304-Cu bimetallic joint exhibited a UTS of 290 MPa and 0.2% YS of 175 MPa, outperforming WAAM-deposited pure Cu and demonstrating failure in the Cu region rather than at the interface. Radiographic examination confirmed minimal porosity within acceptable limits, demonstrating that defect-free and reliable SS304-Cu joints can be systematically achieved through CMT-based WAAM.</p></div>","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"35 Focus—Space","pages":"38554 - 38563"},"PeriodicalIF":2.6,"publicationDate":"2026-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149214589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To clarify the respective microstructural characteristics, uniaxial hot compression tests were performed to explore the high-temperature deformation responses of 7050 aluminum alloy. A DRX kinetic model was established, and electron backscatter diffraction (EBSD) was used to analyze the microstructural evolution, aiming to reveal its underlying mechanism. The results demonstrate that the Avrami exponent is approximately 2, indicating relatively limited nucleation sites. EBSD analysis identified three distinct forms of CDRX: isolated grains at curved grain boundaries, grains formed by subgrain fragmentation, and grain clusters formed by subgrain rotation near grain boundaries. In addition, GDRX was observed at low strain rates, producing grain sizes 2-5 times larger than those of CDRX grains.

The grain growth behavior of the four Mg-Ga alloys under long-term thermal exposure exhibits isotropic characteristics. Even after holding at 673 K for 120 min, the grains of the four alloys remain equiaxed, and no abnormal grain growth is observed. The grain growth activation energy of the four alloys in the low-temperature range is lower than that in the high-temperature range (activation energy in the low-temperature range: 12.7-26.7 kJ <span>({text{m}text{o}text{l}}^{-1})</span>, and in the high-temperature range: 57.6-62.6 kJ <span>({text{m}text{o}text{l}}^{-1})</span>), and the increase in Ga content is beneficial to improving the microstructural stability of the alloys. The as-rolled Mg-5Ga alloy demonstrates excellent thermal stability with a remarkably low grain coarsening rate constant (<i>k</i>) of merely 1.55 during isothermal holding at 673 K. The diffusion of Ga and Mg atoms leads to grain growth in the alloy sheets, while the c-axis of the grains deviates from the ND direction of the sheets, weakening the basal texture. The addition of Ga atoms affecting the diffusion of Mg atoms at medium-to-high temperatures may be the reason for avoiding abnormal grain growth. The enrichment of Ga element at grain boundaries is a crucial reason for the improved stability of the alloy.</p></div>","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"35 41","pages":"42263 - 42276"},"PeriodicalIF":2.6,"publicationDate":"2026-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149338451","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
