By integrating friction force curves with changes in surface morphology, the surface damage characteristics of SiC grains are examined. The evolution of subsurface damage (SSD) within the workpiece is investigated by analyzing the lattice phase transformation and dislocation evolution inside SiC. Synthesizing the evolution patterns of both subsurface and surface damage, the damage evolution mechanism of SiC abrasive grains is elucidated. Analysis indicates that at a grinding speed of 100 m/s, the process is dominated by surface wear, representing the most favorable condition for grinding. At this speed, the internal damage of SiC initially expands in a “flower-like” pattern under the applied load. As grinding proceeds, the petal-like expansions coalesce, and the damage propagates inward along the grinding trajectory. The leading-edge damage exhibits a conical failure mode, while the region behind the cone displays a horizontal damage pattern.

Pigments were synthesized from cadmium salts (chloride, sulfate, nitrate, and carbonate) using sodium sulfide or elemental sulfur as sulfur sources. Two synthesis routes were applied: (1) precipitation of the pigment from solution, followed by filtration, drying at 60 °C, and calcination at 600 °C in acidic and alkaline media; and (2) direct reaction of cadmium carbonate with sulfur at 600 °C. The materials were characterized using Raman spectroscopy and X-ray photoelectron spectroscopy (XPS). The zeta potential of the particles was measured at different pH values, and dispersion stability was evaluated by turbidimetric analysis (Turbiscan). The obtained pigments were mixtures of compounds, with cadmium sulfide (CdS) being the predominant component. The chemical composition depended on the synthesis route and the calcination process. A correlation was found between the electrokinetic potential, sedimentation stability, and chemical composition of the pigments. Calcination significantly affected surface properties, while the presence of chloride, sulfite, sulfate, and carbonate species modified the electrokinetic potential.

The behavior of the specimens is studied in both the as-received state and after annealing. Stress–strain curves of the alloys are determined as a function of strain rate as well as the plastic flow stress at 20% true strain. It is shown that the strain rate dependence of plastic flow stress in the range of <span>(10^{3} - 2times 10^{4},hbox {s}^{-1})</span> is weak, and no increase in yield strength is observed with increasing strain rate in this range. With the decrease in impurity concentration in annealed copper from 0.1 to 0.03 wt.%, no increase in yield stress with increasing strain rate is observed either. The yield strength of the alloys decreases with increasing annealing temperature, but for annealed copper with medium and coarse grain sizes, the yield strength values differ by no more than 10%. A decrease in grain size perpendicular to the deformation axis, as well as an increase in dislocation density within the grains, is found using electron and optical microscopy. Our findings imply that the weak strain rate sensitivity is likely related to the absence of twinning and recrystallization during deformation. A good agreement is shown between the experimental strain gauge data and the finite element simulation results using experimental stress–strain curves obtained by the standard Kolsky method.</p></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"61 21","pages":"14891 - 14912"},"PeriodicalIF":3.9,"publicationDate":"2026-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147751178","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
