The SEM results show that with the increasing of doping coppers, the V2O5 grains became more flat and smooth.

The grain size varies from 10 µm to 80 µm.

If the content of PTW is more than 5wt%, the binding force between PTW and PTFE decreases gradually, and the PTW can be brushed off easily, and so, the free whiskers and their scraps in the interface would actually enhance grain abrasion, which increases the friction coefficient and the wear rate.
When the amount of rare earth is too high, the treatment surface whisker exist chemical adsorption and a large number of physical adsorption layer, which make the weak phase appear between the whisker and the matrix.

The basic transducer body integrated with a cup shaped grinding wheel and mounting flange with sufficient number of boltholes for mounting on the spindle of a machining center is illustrated in Fig. 1.

Introduction A large number of engineering practice and test results showed that the amount of moisture content and stress condition have great influence to the shear strength of soil.

However, the SPS process has a number of advantages over similar sintering methods such as HP.
Grain boundaries are visible in the pure Mg sample after etching with 2 g of picric acid and 50 ml of ethanol (Fig. 3a).

Comprehensive Model 2.1 Anisotropy Anisotropic behavior is common for many soils and rocks due to preferred orientation of mineral grains or bedding planes.
Although there are a relatively large number of parameters in the proposed failure criterion, all of them can be determined in tests.

Introduction Some of the major driving forces for the development of Al–Si cast alloys are the superior wear resistance, low coefficient of thermal expansion (CTE), high corrosion resistance, high strength to weight ratio, excellent castability etc. which make them potential candidate materials for a number of tribological applications in automobiles and other engineering sectors.
In hypereutectic alloys in which primary silicon can be present in several different forms like star-shaped, polyhedral and dendritic with unmodified plate or needle like eutectic Al-Si and few primary α-Al grains.
