Nanotribology, one of the new areas developed with the nano-science and technology, aims at the friction, wear and lubrication at the moleculor and / or atomic scale. In this paper, following illustrating the background of arising of nanotribology, the si

The flow in the crucible during ACRT process is calculated with SOLA-VOF(a solution algorithm based on the concept of the volume of fluid).The effeCts of the rotation acceleration, the diameter,and the maximum rotation sped as well as its lasting time, of

Acoustic emission (AE) study on SiC/Al model composite which made the fracture sources simple has been carried out. AE characteristics from fracture sources have been measured. Three kinds of fracture in SiC/Al, fiber fracture, fracture of interface betwe

Ultramicrohardness tester has been used to test the hardness in the different microzones ofaluminum matrix composites reinforced by fibers or particulates. It is found that the ultramicrohardness value increases apparently near the interface, and that the

An in-situ tensile experiment in a SEM and finite element method have been made into the deformation and damage behaviors, the strain and restrain fields at the crack tip under the different Ⅰ+Ⅱmixed mode ratios in an Al single crystal.The results show th

The investigated material was treated in hard state. Uniaxial tensile or compressive plastic deformation caused an increase in the yield strengths and a decrease in the half width values for the unpeened surface and the base material of the shot peened sp

The fusing temperature of nanometer Ag particle has ben measured,and the surface energy of Parable with varied radius has hen obtained in the paper.By applying of solid theory,the law of surface energy varying with the particle radius and the temperature

The strain and temperature rise within the adiabatic shear bands (ASB)produced by orthogonal cutting in 30MnCrNiMoB steel are calculated. The results show that the values of the strain and the temperature rise are inereased with increasing of the cutting

The magnetic properties of soft magnetic alloy with rectangular loop have been investigated.It is found that the core loss spectrum has the fractal structure. The effect of heat treatment condition and sheet thickness on the fractal dimention D is studied

A systematic study on the effect of physical aging and cooling rate to α-relaxation peak are carried out in PVC. It was said that α-peak and Tg are not the same concept. Both are close connected with amorphous polymer state, but different behaviors were p

The friction and wear properties of Si3N4/steel rubbing pairs were investigated by using a Pin-on-disk tribometer. Water, liquid paraffin and a commercial cutting fluid were uSed resistively as lubricants. The selected speed and load ranges for the tests

Peeling behaviour of metal-to-rubber bonded comPOsite in vulcanization was investigated.Thc effect of different grades of carbon black and its loading in bonded rubber compounding on the double oriented 180°peel property of the same adhesion sample was ex

The shaped factor of spherical nucleus is calculated. The relationship of grain size and current density is derived in the condition of homogencous nucleation without grain swallowing. Critical current densities for Ph, Sn, Cu, Fe, Ni and Al in the fabric

The misfitting dislocations at the interface between bainite ferrite and retained austenite in upper meta-bainite and lower meta-bainite, which formed in Si-containing steel, were studied by using transmission electron microscopy. It was found that they w

Dislocations were emitted from a crack tip, and nucleation, blunt and propagation of a microcrack with a nanometre in size are studied through in situ tensile test for thin foil speCimens of ODS ferritic steel by transmission electron microscopy (TEM). Th

The strength behavior and crack propagation of Ca0. 5 Sro. 5Zr4(PO4)ceeram ics after thermal shock are shown to depend on the thermal expansion coeffcient and axial thermal expansion characteristic of the ceramics. It is different from A12O3 ceramics that

(Pb0.5Ca0.5)TiO3(PCT) ceramics was synthesized by conventional POwder processing techniques. After long time annealing at 1000t, the dielectric behavior of both samples as sintered and annealed were inveStigated. The sample annealed showed less frequency

There exists a ductile to brittle transition for polypropylene caused by variation of loading rate at constant temperatures. With increasing loading rate, the material fractures by transition from plastic to brittle ways. Increasing temperature makes the
