The effects of different annealing technique on the static recrystallization, microstructure, mechanical properties and fraction mechanism of AZ31B magnesium alloy sheets are investigated. High toughness and high formability of AZ31B magnesium alloy sheets are achieved by researching how to optimize annealing techniqu…
The present study aims to understand the evolution of microstructure leading to nano/ultrafine grain formation during cyclic thermal process. A commercial grade of AISI 304L austenitic SS was cold rolled which resulted in a creation of a dual microstructure having strain induced martensite (43%) and heavily deformed r…
The current work has investigated the texture development in an austenitic Ni-30Fe model alloy during deformation within the dynamic recrystallization (DRX) regime and after post-deformation annealing. Both the deformed matrix and DRX texture displayed the expected FCC shear components, the latter being dominated by t…
Formation process of textures in AZ80 is investigated on polycrystal specimens with different initial textures by plane strain compression deformation at 673 K and 723 K with strain rates between 5.0×10-4s-1 and 5.0×10-2s-1. Three kinds of specimens were taken out from the extruded bars with (direction of the extrusio…
The homogeneous rare earth IR/NR blend applied in tread compound of all-steel TBR tire was investigated,and compare to Russian SKI-3, SKI-5/NR blends and NR.The results showed homogeneous rare earth IR/NR blend had similar vulcanization characteristics, dynamic mechanical properties and heat-aging resistance or even b…
The Nickel-Titanium (Ni-Ti) alloys are the most attractive amongst shape memory alloys (SMA) due to their good functional properties coupled with high strength and good ductility. The transformation temperatures in Ni-Ti SMA can be altered by chemical composition and thermal and/or mechanical treatments adequate to ob…
SiCp/Mg-Al composites with 5μm 2wt.% SiC particles as reinforcement were prepared under the protection of inorganic flux. The microstructures, textures and components of the composites were investigated using optical microscope (OM), scanning electron microscope (SEM), X-ray diffraction (XRD) and backscattered electro…
The surface topography and growth behavior of self-assembled monolayers (SAMs) formed from vinyltriethoxysilane (VTES) at a constant temperature (20°C) on silicon dioxide substrates were investigated using atomic force microscopy (AFM). Two methods for silanization were introduced: vapor phase deposition and depositio…
Self-protection of flux-cored wire surfacing is a new way to improve mechanical parts surface properties, and can improve mechanical equipment in the harsh condition of wear-resisting, corrosion resistant, high temperature resistant and oxidation resistance abilities. This paper based on this technology, research on i…
Nanocrystalline Ni and Ni-P alloy with grain size down to 6 nm were processed by pulsed electrodeposition. The as-deposited materials, possessing a strong fiber texture, were tested in tension at different temperatures and strain rates. Both materials exhibited low temperature superplasticity but with significant diff…
A new technique has been developed by infiltration during casting process to AZ91D magnesium alloy part. Through a melting process a alloyed surface layer was formed on the surface of the part in casting process, and the surface layer helps improve the corrosion resistance. The macro morphology, thickness, microstruct…
Warm rolled deformation is one of deformation technique to improve the strength of steels through the refining grain size of ferritic microstructure. In application, low carbon steel which used in structural industry need some protection against corrosion attack, cathodic protection is usually applied combining with c…
A novel experimental investigation of both high and medium stacking fault energy bi-crystals of aluminum and copper, respectively, show that orientation, grain interaction and material are all key factors in the stability of some ideal rolling texture components. Ideal {110} or {112} orientations obtained from high pu…
The problems of 3Cr2W8V steel concave die forging production must be solved, such as too many procedures, high cost and mold crack. Through the use of a warm extrusion forming method it could make one-off forming die cavity come true, more practical warm extrusion forming parameters and extrusion die structure paramet…
Features of the deformation process by cold radial forging of tube billets from Zr-1%Nb alloy were reconstructed on the basis of X-ray texture data. The cold radial forging intensifies grain fragmentation in the bulk of billet and increases significantly the latent hardening of potentially active slip systems, so that…
An experimental study of the microstructural and texture evolution attending recrystallization of Nb-Ti stabilized ferritic stainless steel is presented. Two specimens with different Nb-Ti compositions, TCS345 and B4003, have been selected for comparison. The result shows that, after annealing at 750 °C for 5min, the…
The three common frequency selective surface (FSS) structure, i.e. ring, crosses and Y-aperture which have the same center frequencies are designed, then the three FSS structures are placed at absorbing materials to form complex absorbing structures which are simulated by means of spectral domain approach. Therefore,…
Current status of the direct spinning production lines in high unit capacity of the polyester textile fibers in China are investigated, as well as the status and development of flexible production technique.
This study utilizes tungsten oxide as the research subject and investigates changes between different argon/oxygen gas flow ratio and deposits on ITO substrates through RF reactively sputtering. Propylene carbonate (PC) is further mixed with LiClO4 for the preparation of electrolyte. After packaged into components, el…
Due to the shortage of traditional pre-cross linked particulate, such as suspension property, temperature and salt tolerance, and injectivity, this paper developed hydrophobic association polymer pre-cross linked particulate based on hydrophobic association polymer. The performance evaluation of rheological behavior,…
