Quasicrystals are a special group of Hume-Rothery phases with strong Fermi Surface-Brillouin Zone interaction. The research along this direction is extensively carried out to understand their various specific behaviors. With respect to this, the present p

The surface blistering and flaking erosion of amorphous alloys Fe77B16Si5Cr2 and Ni78B14Si8 under high-dose He+ bombardment, and helium depth profiles in materials were reported.H+ ions were implanted with energy ranging between 80 and 120keV to a dose of

Some strips of five Al- (2-10) Wt-% Cr alloys were made on the rapid cooling apparatus with a monoroller.The calculated average cooling rate was about 3-4 x 105℃ / s.The microstructure and the phase consistance of the alloy were studied by XRD, TEM, elect

In this paper, KF stability equation is further analysed, and a new interface statility criterion, obtained. Furthermore, the united criterion of interface stability is interpreted. It is found that not only high solidification velocity but very high tem

Liquid extrusion process, which has been newly developed, can form tube, bar or shape products by only the single process. The process possesses the characteristics of the liquid metal forging and the solid extrusion, including crystallization under pres

The structure parameters of crystalline phase—α-Fe and amorphouse phase in Fe73.5 Cu1Mo3Si13.5B9 annealed alloys have been studied by using XRD method. The effect of these structure parameters on initial permeability has been discussed. The width and thic

A method was used to study the formation and growth of the nuclei for plating Ni-P film to transform from crystal state to amorphous state, that is, to superpose a small current square wave on the cathodic current and to measure the disurbed poential-time

The short crack propagation behavior in 8090 Al-Li alloys at various aged conditions (underaged, peakaged, overaged, naturallyaged) and the effects of the notch radius on the short crack propagation have been studied. The results show that the fatigue cr

In-situ observations by using transparent organic model system CBr4-8.4wt-%C2Cl6 on constrained melting processing of lamellar eutectic to study melting interface morphology. It is found that the melting interface is closer to the heater than that of moti

Pb(Fe1 /2Nb1 /2O3 (PFN) ferroelectric ceramics with pure perovskite phase were prepared by direct formation method. Some of the samples were annealed at 900℃. The dielectric properties were measured. The results indicated that both unannealed and anneale

The structural evolution of nanocrystalline intermetallic compounds TaC and TaSi2formed by mechanochemical reaction was studied by XRD, TEM and SEM. Results show that TaC and TaSi2were directly synthesized from elements through interdiffusion process. The

In this article, collagen protein was extracted from bovine tendon by enzyme digestion and was spread to form membrane materials. Then the materials were crosslinked by formaldehyde to form guided tissue regeneration materials. The results from the test

The surface of natural collagen was modified by low temperature plasma with oxygen and argon seperately. Natural collagen was extracted and purified from bovine tendon by enzyme digestion.Crosslinked collagen membranes were then prepared from a 0.8% (w /

Enthalpy change( H) corresponding to different annealing temperaturewas systematically was measured by using DSC in amorphous polymer PVC (a-PVC). By introducing a concept on structure temperature(θ), entropy change △(S) was easily obtained. On the basic,

A sysmatic study on the effect of physical ageing on α-relaxation peak was carried out in amorphous polystyrene (PS). Some interesting results about the change of behavious with ageing were obtained as follows: α-peak temperature keeps constant and the

In this paper, the loading and loading-unloading tests of CALLand CALL(CCVC) under tensile impact have been carried out by a self-designed Rotating Circular Disk Tensile Impact Apparatus.The quasi-static tension and short beam bending tests are performed

In order to simulate the interfacial reaction of composites, three Al / SiC multilayer systems with TiC, Al2O3 and SiO2 as the reaction barrier layers have been investigated by means of DTA and XRD.It has been showed that after 700 ℃, lh heat treatment, t

The black solid powder consisting of ultrafine diamond, graphite and amorphous carbon was synthesize using the detonation method of TNT / RDX (50 / 50) mixed explosive, and the Ni-black powder electrodeposited composite coating (ECC) was prepared. Experim
