Lamellar structures formed with different size were found in the TiAl(Mn) two phase alloy (10). HREM observations show that the a2-γ interfaces of the lamellar structures with micrometer and nanometer seales are different from each other. The a2-γ interfa

The critical stress τc. to drive dislocations for the stress field generated either by micro indentations or oxygen precipitates in Si crystals is researched. The results show that the indentating or the oxygen precipitate with a group of near dislocation

By measuring the temperature dependances of resistance of amorphous Ni72-xSi15B13+x(x=0,2,4,6,8) alloys, it has been found that there is a linear relationship of the resistance with temperature above room-temperature, and the room temperature resistivity

A chemical plating method was used to coat WC and C powder with Ag. The experimental results shown that this method could improve the infiltration between WC, C and Ag powders and make phases distributed evenly. The electrical contact materials, which we

The effects of hydrogen on the α2/β transus temperature and lattice constant in super-α2 alloy are studied by thermal dilatometer and X-ray diffractometer, respectively. The results show that, the a2/β transus temperature is decreased and the lattice cons

A microstructure consisted of a NiAl martensite as a matrix, γ'-Ni3Al distributed along the grain boundaries of the matrix and with a network appearance, and a few retained β-NiAl was resulted from annealing at 1523K for 2h in a rapidly solidified Ni-34.6

Based on medium Mn steel, a new as-cast wear-resistant austenite-bainite steel with nodular carbides can be obtained by method of modification. This steel has high strength-toughness and wearresistance. Therefore, it is a new type of wear-resistant materi

From the trends of material development, the importance and necessary of nano-material research was discribed in this paper. The proposal on nano-materials will bring up new scientific contents on material sciences, material processing science, material

A review was given of the lubrication of ceramics, also the wear and friction properties of ceramics were dealted with. It is well known that conventional lubricants and additives could lubricate metallic surfaces successfully. The lubricants and additiv

FeZn ferrites with different contents of Zn were prepared in alkaline aqueous solution including suitable addatives. The formation mechanism and magnetic properties of FeZn ferrites have been studied. The process of the formation of ZnxFe3-xO4 can be desc

Large power density of SnO2:Sb electric heating films are prepared by use of chemical purity materials, and their structure is analyzed. The effects of Sb contents, as well as spraying liquid concentrations and annealing treatment, on room resistance valu

Effect of doping V2O5 on resistance and stability of SnO2 element is studied. The experiment results show that the resistance drops when the V2O5 content is fewer than 0.56w.%, and the resistance rises when the V2O5 content is more than 0.56w.% and the st

In this paper, it has been succeeded to join ZnO ceramic with RS Tin-based active solders at lower temperature in air for the first time. The result of shear strength of joints shows that shear strength of joint was enhanced obviously by using RS Sn-based

In order to arrive at a high interface bond strength between the CBN grit and the borosilicate glass bond and eliminate any harmful chemical reaction during firing, the interface reaction process, interface composition and structure between Nb cladding an

The oxidative stabilization process of mesophase pitch fibers was monitored by thermogravimitry (TGA) measurements at several temperatures, so the lowest temperature, at which the process could be carried out, was determined. It is noted that below the so

Two kinds of epoxide resins made in China have been characterized by time-of-flight secondary ion mass spectromctry (TOF-SIMS) combined using thin-film silver cationization. Authors have found some different epoxide resin components, their possible struct

SP self-degradable starch-plastics film is prepared by polymer blending PVA with starch.The sample with different compostition are dealed with structure characterization, electronic scanning, mechanical property examination, viscosity detemination and dat

The growth process of the reactive self-composing material (RSCM) and the influence of the process parameters on the structure and properties of the RSCM are described and discussed. Results have showed that the A12O3/Al ceramic matrix composite(CMC) can

At the optimized composition of the PVA/Water/alumina, the thin sheets of fluorophlogopite mica powder doped with alumina were stacked with the thin sheets of alumina matrix, rolled to form laminated material. Sintered at 1600℃ for 40 minutes, the thin sh
