Recently, silicate materials have received attention as with promising applications in the bioceramics field. A recent study aimed to investigate effect of forsterite (Mg2SiO4) addition biogenic hydroxyapatite, Ca10(PO4)6(OH)2, on phase formation, physical and mechanical properties, biocompatibility produced composites. Different proportions forsterite, 10 40 mass%, were added hydroxyapatite obtained from fish bones prepare target Various techniques, such X-ray diffraction analysis (XRD),...
In the present study, influence of processing parameters friction stir welding on corrosion rate welded joints aluminium SiC–Gr hybrid composites was investigated. The experimental results indicate that resistance increases at high (traverse) speed and/or low values rotational speed. These variations occur as a result changes in joint microstructure, where fine grains are developed consequence relatively heat input and fast cooling to room temperature by ambient air associated with speeds....
Abstract This article is an attempt to optimize the surface finish of roller burnished nonferrous components. The effect both burnishing force and number tool passes was studied, while other parameters were kept constant. Two materials—namely, pure aluminum (Al 99.85) high machining brass (Cu Zn 3g Pb3) bars—were considered. A fuzzy logic model used achieve optimum for finish. predicted that values finish, under considered conditions, may be obtained using a 25 Kgf with four aluminum, 30...
The fabrication of ceramic composites with low thermal expansion and excellent mechanical properties is essential for barrier coating (TBC) applications. For this purpose, using the sol-gel process, novel were developed by combining varying weight percentages β-spodumene (0–20 wt%) zirconia toughened alumina (ZTA). influence addition on densification, phase composition, microstructure, mechanical, thermal, fracture behavior studied was investigated experimentally numerically. Increasing...
Abstract Enhancement of microstructure and mechanical features the hybrid aluminum matrix composite (HAMC) prepared by stir-casting process (SCP) is quite significant for failure prevention during service. In this work, circular rod reinforced with particles alumina (Al 2 O 3 ) 50 μm, graphite (Gr) 40–100 µm fabricated SCP was adopted. This Al1050/Al /Gr subjected to severe plastic deformation using equal channel angular pressing (ECAP) at room temperature show impact on composite. Grain...
Zirconia-toughened alumina (ZTA)/Al2TiO5 composites were prepared via a sol–gel route. The samples uniaxially pressed and pressurelessly sintered at 1650–1700 °C for 1 h. microstructure, densification, X-ray diffraction patterns of the ZTA/Al2TiO5 investigated, their mechanical properties, thermal coefficient, shock resistance characterized. addition Al2TiO5 hindered grain growth particles enhanced relative density, Vickers hardness, bending strength compared with pure ZTA samples. fracture...
Abstract In the present study, Al 2 TiO 5 was prepared via sol–gel technique then sintered at 1000°C to 1300°C for 1 h. The thermal stability of formed ceramic bodies explored. densification parameters, microstructure, and phase composition were examined, mechanical properties coefficient characterized. study revealed presence alumina residuals up 1100°C. Phase observed in 1300°C. vitrification behavior improved by increasing sintering temperature. expansion samples enhanced formation...
In the present study, La2Zr2O7 was used as a coat for stainless steel alloy. Lanthanum zirconate sprayed using plasma spray technique. The preparation and characterization of studied. Hot corrosion surface conducted in (1:1) V2O5 / Na2SO4 molten mixture at 900oC 50 100 h. results showed that attacks heavily after Depending on nature salt, can considered either strong basic oxide or acidic oxide.
Aluminum oxide-based thermoluminescent dosimeters are very common and possess many applications in radiation measurements. In the current work, three patches of aluminum oxide doped with La2Zr2O7 were prepared, namely La1, La2, La3, containing 0.5, 1, 2% concentrations La2Zr2O7, respectively. Dosimeters tested for their response to gamma radiation. Linear curves doses over range (0.5-60) Gy plotted. Fading studies revealed a decrease total T.L. output first ten days after irradiation.
