Impact of GGBFS and Pond Ash on the Strength and Durability of Concrete Mixes
Published 2026-02-01“…Durability assessments revealed a decline in water absorption ( R² = 88.05%, MAPE = 5.45%) and acid attack resistance (R² = 99.83%, MAPE = 0.58%) with increasing GGBFS and Pond Ash content, primarily due to increased porosity and altered microstructural characteristics. Microstructural analysis confirmed reduced hydration density and weaker bond formation at higher replacement levels. …”

Technology of Laser Cladding Ceramics on Heat Resistant Steel Surface
Published 2020-02-01“…Heat resistance steel type of H13 is used for the aircraft structure parts whose working temperature is 400~500℃ Moreover, it is required to wear resistance for the parts in some special service environments In order to solve the problem of wear failure in hot work dies during service, a low power laser type of Nd:YAG was used to cladding SiC ceramics on the surface of H13 steel The macroscopic feature, microstructures and compositions were observed by the metalloscope, scanning electron microscope and energy depressive spectroscopy Experimental results indicated that that the cross sections of the cladding sample were markedly divisional (Clad Zone, Fusion zone, Heataffected zone, Substrate Zone) The microstructure of cladding layer is nondirectional and compact, without obvious crack and porosity and with good performance The homogeneous microstructure of bonding layer is dendrite and equiaxed grain with small size, and the massive columnar crystal grew from the bond line of H13 steel substrate to fusion zone The wear resistance of laser cladding ceramics on heat resistance steel surface is analyzedBesides, a through crack appeared after the scanning speed up to 40mm/min、60mm/min on the cladding layer as the hard and brittle characteristic of SiC ceramics and the difference of thermal expansion coefficient between SiC ceramics and substrate; The above research results provide some theoretical support for improving the surface wear resistance of aircraft heatresistant parts.…”

Study on the Corrosion Behavior of Rare Earth / Niobium Microalloyed Steels in Marine Atmospheric Environments
Published 2021-06-01“…For providing the data support to design and develop microalloyzed steels, the corrosion behavior of rare earth microalloyed steels and niobium microalloyed steels in marine atmospheric environments was investigated by the means of surface microstructure characterization, alternative wet/dry cycle test, neutral salt spray test and electrochemical measurements.Furthermore, the corrosion resistance of microalloyed steels was compared and analyzed.Results showed that the microstructure of microalloyed steels consisted of ferrite and pearlite, and niobium microalloying favored the refinements of the grains and hindered the formation of pearlite.The rust layer was composed of for γ-Fe2O3 and γ-FeOOH, which had no obvious protective effect to the substrate.With prolonging exposure periods, γ-FeOOH gradually transformed to α-FeOOH, enhancing the protective effect to the substrate.The corrosion current density of rare earth/niobium microalloyed steels declined, and thus the corrosion resistance of those two kinds of steels were improved.After a long period of corrosion, the grain refinement of niobium microalloyed steel was beneficial to increase the densification of the surface rust layer and the content of α-FeOOH was relatively high, then further the corrosion rate was reduced.Hence, compared with rare earth microalloyzed steel, the niobium microalloyed steels presented a better atmospheric corrosion resistance.…”
