The results show that the deposited layers obtained at the electrodeposition time of 3 min, the electrolyte temperature of 50 °C and the output voltage of 2.5 V exhibit small grain size and good adhesion to the substrate. Meanwhile, the effects of the two-component additive and the three-component additive on the microstructures, surface roughness and electrochemical behavior of copper foils are studied. The x-ray diffraction results reveal that copper foils prepared by simultaneous introduction of 0.06 g/L bis-(3-sulfopropyl)-disulfide and 0.08 g/L collagen possess a dense and homogeneous structure with the smallest grain size and the lowest roughness, which is diminished by 26.17 %. The electrochemical results indicated that the SC additive had an inhibitory effect on the deposition of copper ions, while the SH additive exerted depolarizing effect in this electrolyte system, accelerating the deposition of copper particles, which was attributed to the antagonistic interaction between bis-(3-sulfopropyl)-disulfide and hydroxyethylcellulose that hindered the preferential adsorption of the additive at the surface protrusions, resulting in the decrease in the refinement effect of the bis-(3-sulfopropyl)-disulfide additive. Under the optimized process parameters, the increase in the deposition rate of Cu2+ balances the relationship between nucleation and growth of copper ions, which ultimately produces the copper foil with smooth surface and low roughness.","PeriodicalId":18366,"journal":{"name":"Materialwissenschaft und Werkstofftechnik","volume":"56 2","pages":"235-250"},"PeriodicalIF":1.2,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143389306","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}

The fabricated composite were characterized for physical (density, void content, hardness), mechanical testing (tensile, flexural, inter-laminar shear strength, impact strength and fracture toughness) and thermal properties. The experimental result indicated varied rate of deterioration for tensile strength of the composites and the maximum tensile strength 69.51 MPa was obtained for blast furnace slag (3 wt.-%) and date palm fiber (30 wt.-%) hybrid composite. The optimum flexural and inter laminar shear strength has been obtained to be 85.72 MPa and 9.43 MPa for 7 wt.-% blast furnace slag-filled date palm fiber-epoxy hybrid composite. Similarly, in case of fracture toughness, blast furnace slag-filled composites, fracture toughness increases by approximately 20 %, 28 %, and 38 % respectively over unfilled composites.

As a consequence, a significant grain refinement effect and a gradual accumulation of lattice strain during the progress of cyclic heat treatment are observed in relation to an evolution of the regions of extremely low misorientation angle in the aluminium matrix. Apart from quench-in strain, the presence of grain boundary iron aluminide phase, possessing a different coefficient of thermal expansion than that of aluminium matrix, appears to be an additional reason for gradual lattice strain development. In addition, a preferred growth of (202) plane along [101] direction towards the final stage of cyclic heat treatment (four cycles) is also revealed. As a result of gradual lattice strain accumulation and grain refinement effects, the hardness of commercially pure aluminium is found to be considerably enhanced (98 HV 10) after 4 cycles of heat treatment as compared to an initial hardness (36 HV 10) in annealed condition.","PeriodicalId":18366,"journal":{"name":"Materialwissenschaft und Werkstofftechnik","volume":"56 2","pages":"201-211"},"PeriodicalIF":1.2,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143389291","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}

The input variables included cutting velocity, depth of cut, and feed rate, while the output responses measured were surface roughness (Ra) and cutting force (Fc). The influence of these process variables was determined through analysis of variance (ANOVA). ANOVA results revealed that cutting speed, feed rate and depth of cut were impacting the average surface roughness by 36 %, 29 %, and 31 %, respectively and influencing the cutting force by 2 %, 16 %, and 72 %, respectively, during turning operation. Empirical models for predicting cutting force and surface roughness were developed using the Taguchi meta-heuristic algorithm. The optimization process resulted in a significant reduction in surface roughness, with Ra decreasing by 17 % and a notable decrease in cutting force, Fc, by 8 %.
