Abstract This study investigated the mechanical properties and effects of volume fraction for carbon fibers (CF-VF), polypropylene (PPF-VF) aramid (AF-VF) with a fixed aspect ratio 650 fibers, 400 900 in hybrid fiber-reinforced concrete (HFRC). Furthermore, compressive, splitting tensile flexural tests were carried out to obtain optimal total three types as well between CF-VF, PPF-VF AF-VF. In addition, stress–strain curves normal HFRC examined explore whole process. The results indicated...
In this article, a protective Ni–Co alloy coating was prepared on AZ91D magnesium which pretreated with electroless plating. The surface morphologies, microstructure and chemical composition of the coatings were studied using environmental scanning electron microscope, X-ray diffraction energy dispersive spectroscopy respectively. morphologies analysis showed that possessed cone shaped grain congeries formed face centred cubic solid solution. revealed content cobalt element in ∼31 wt-%....
High chromium cast iron alloys are widely used to produce wear resistant components. However, formation of the large carbides restricts their applied range for components by traditional solidification techniques. The gas atomization is an effective approach refine structures, improve properties and extend application field. Based on study structure evolution atomized powders Fe-25Cr-3.9C alloy, this paper investigated alloy with addition Ni B elements. It found that elements make more...
In order to study the damage mechanism under different stress states of aluminum alloy components, two kinds representative triaxial were adopted, namely notch tensile and pure shear. The results showed: During test, triaxiality in least transverse-section was relatively higher. With increasing applied stress, volume fraction microvoid root constantly. When reached critical value, specimen fractured. shear almost came up zero, there no micro-void but localized bands within specimen. resulted...
We proposed a method to tune the wettability of solid surface by changing its roughness. With specific designed micro square-pillar arrays, apparent contact angle hydrophobic can be continuously adjusted from intrinsic above. The samples were fabricated combining silicon micromachining and self-assembled monolayer modification. experimental results closer Cassie's theoretical predictions on super-hydrophobic surfaces than that Wenzel's. same (CA, 110/spl deg/) flat surface, CAs tuned deg/...
This paper uses the small punch test (SPT) to some performance of materials, have put forward basic method material tensile mechanics from an inverse FE with SPT. The research shows that and stress each district welding seam can be accurate determined by test. has offered theoretical foundation for characterizing welded joint mechanical heterogeneity
Abstract The characteristics of instability have been investigated on two low nickel austenite stainless steel at the temperatures 950–1200 °C through uniaxial tensile test and unload test. results show geometrical is not concurrent with load in high temperature tensile. deformation specimens are uniform before instability, then appear non-uniform some local area specimen but they do directly lead to geometric instability. With increase temperature, strain hardening exponent n both no...
By using a thermal simulator this work investigated grain growth behaviour of Ti+Nb stabilized 12%Cr ferritic stainless steel at high temperature. The results showed that the rate was less than 1.8μm/s temperature 1200°C, but it suddenly became very and reached about 50μm/s when 1250°C. Analysis indicate is affected by small particles on boundaries, exponent 3.3. Moreover, activation energy above Compared with 27Cr containing only 0.14%Nb, greater, initial rapid higher.
The present work explores an environmental friendly method for forming conversion coatings on AZ91D magnesium alloy by applying a static magnetic field. An amorphous / nanocrystalline coating was developed alloys in phosphate-permanganate aqueous solution under 0.5 Tesla examinations of the microstructure and phase compositions reveal that is composed structure with mean size less than 10 nm. In corrosive chloride solution, amorphous/nanocrystalline artificial defect were investigated...
In this paper, the structure evolution of Fe-7.5at.%Ni thin strips under near-rapid solidification conditions was investigated. One-dimensional (1D) heat transfer model used to calculate cooling rate strips. The calculated results showed that decrease distance from surface, made effective increase sharply, which led a higher rate. Moreover, experimental size columnar crystals increased clearly by and equiaxed grains appeared when above 0.75mm. addition, it is indicated even strip thickness...
