A detailed investigation has been made of fracture characteristics andmicro-deformation mechanism of a single crystal superalloy during high cycle fatigue at800℃.There are two types of fracture modes in morphology to be found,one is the cleavageand the ot

Two kinds of intermetallic alloys,based on Ti_3Al and Ni_3Al,have been em-ployed to investigate the mechanical properties and the fracture behaviors at room temperature.The fracture of the alloy based on Ti_3Al is generally characterized by transgranular

Stress intensity factor for a sharp crack is used to reflect the crack initiation froma three point bend notched specimen.Structural steel 13SiMnNiCrMoV is studied in this paper.With R=0.1,f=100Hz and the specimen size B×W×L=12.5×25×117mm,the nominalstres

The effect of aging on the structure and properties of rapidly solidifiedAl-2.4Li-2.4Cu,Al-2.4Li-2.4Cu-0.3Zr and Al-2.4Li-2.4Cu-0.7Zr alloys has been studied byusing tension and TEM.The experimental results show that aging velocity and tensile strengthof

By using the way of brush and laser melting Co-base alloy was coated on thesurfaces of stainless steel 1Cr18Ni9Ti in this paper,The hot corrosion resistance is obviouslyimproved.The microstruture,mechanism of hot corrosion and corrosion products of laser

The wettability and the interfacial reaction between molten ternary alloysCu-Sn-M(M=Ti,Zr,V,Cr)and various type of silicon carbide,such as sintered SiC and sin-gle crystal α-SiC,were investigated by the sessile drop method,EPMA and SEM.It was discov-ered

Unlike powder-binder composites,amorphous brazing foil is a 100% densebrazing filler metal that can be punched to exact joint shapes.The amorphous brazing foilshaving composition Ni76Cr13.9P10.1,as nuclear reactor brazing filler metal,have excellentweldin

Considering initial transition processing is important in studying pattern selec-tion because the non-linear dynamic conduct is dependent upon early stage and path in crystalgrowth processing.The initial transition processing has been analysed in detail a

Extension of solid solubility of RE(RE=Sm,Gd,Tb,Dy,Er)in Ag andAg_3RE metastable phases with hexagonal lattice was observed in rapidly-solidified silver-richAg-RE alloys.Followed by aging process,the metastable super-saturated solid solutionturned into eq

By using DSC,XRD,TEM,Mossbauer spectrum as well as magneticmeasurements,the influence of copper addition on intrinsic magnetic properties andcrystallization behavior of amorphous FeSiB alloy has been experimentally studied.Resultsshow that with replacemen

The exchange coupling in NiFe/TbCo bilayers is studied by ferromagnetic resonance(FMR),and the spectrum shows there is a connection with the coupling.The spin resonance peaks will beabsorbed into uniform resonance peaks as the exchange coupling field beco

This paper researched the adulterant effects of Ni-Zn ferrites doped withLa~(3+) ion via the variations of the electrical properties,magnetic properties,temperature charac-teristics and microstructures.La~(3+) can reduce the grain size forNi_(0.41)Zn_(0.6

In a previous paper a new theory of stress-induced crystallization for polymerentangled networks was proposed.It is based on the theory of viscoelasticity with constraints ofentanglement and crystallites engendered by extended and folded-chain crystalliza

Composite particles of PMMA-MAA/PS with microvoid morphology wereprepared by means of soap-free seed emulsion polymerization.The effect of average molecularweight of seed polymer and curing agent on particle morphology were studied under the obser-vation

The mechanical and the thermal properties of BN-Sialon multiphase ceramicswith different BN contents were discussed and researched.The thermal shock resistance of theSialon ceramic is greatly enhanced by introducing BN particles and the high-temperature b

In the present work,a new kind of composite material,Vinylon ReinforceoAluminium Laminate(VIRALL) has been developed by using adhesive technology.Comparedwith the corresponding aluminium alloy,a decrease in density,an increase in strength,good shaping pro
