Cutting Tool used: Inserts of fine-grained tungsten carbide 6% Cobalt substrate with a CVD multilayer coating were used for the experiments.
Taguchi design of experiments (DOE) methods incorporate orthogonal arrays (OA) to minimize the number of experiments required to determine the effect of process parameters upon the responses of the process [5] and L27 OA was used in this study.

Fig. 1 and Fig. 2 show the XRD pattern of both samples, showing the maximum peak of (111) matching with the reference card of CeO2 with number 00-043-1002.
And thus the more charges have accumulated around grain boundaries due to the occurrence of interfacial polarization at lower frequency.

Design parameters: trial-mix strength, cement type, cement content, aggregate type, grain composition, water consumption, sand ratio and so on.

Transition metal sulfides (TMS) form a very important group of materials exhibiting a number of interesting properties.
Nanocrystalline state is responsible of a high volume of grain boundary, and because this is a high-energy region, favors the surface phenomena, like catalytic activity.

Natural selection has favoured the evolution of a variety of shell adaptations in some groups of amoebas, e.g. in Diflugia, the shell is made of tiny sand grains cemented together in a kind of miniature upside-down vase; in Arcella, the shell is constructed from the chitin (protein-sugar compound); in Euglypha, thin siliceous plates are produced and deposited in the outer layer of the amoeba's body.
Conidiophores are reproductive structures that enable some filamentous fungi to produce and disseminate large numbers of asexual spores.

Introduction The study of porous medium has gained considerable momentum in last few decades because of its significant role in many scientific and engineering applications namely geothermal heat extractions, nuclear reactor waste disposal, heat exchangers, electronic components, solar energy storage technology, exothermic reactions in packed bed reactors, storage of grains, food processing, and the spread of pollutants underground etc.
, , , , , , , (4) Where , Ra, H and Kr are stream fuction, Rayleigh number, Inter-phase heat transfer coefficient and thermal conductivity ratio respectively.

When the aging temperature is 425℃, a large number of rolling belt exist in the matrix because reply recrystallization is not enough , so elongation ratio is low.
At this process condition, the alloy had an excellent comprehensive mechanical properties and conductivity propertyof the tensile strength, elongation，hardness and electrical conductivity reaching 549 MPa,15％,82.34%IACS and 215HBW respectively. 3.2 The analysis of one step cold rolling aging organization Fig4 TEM of alloy with rolling as-aging at 475℃ for 16h Fig 5 (a)SEI (b) EDS analysis of small particle in Cu-0.4%Cr-0.2%Zr-0.15%Mg alloy with rolling and aging Fig 6 (a) BES (b)EDS analysis of small particle in Cu-0.4%Cr-0.2%Zr-0.15%Mg alloy with rolling and aging After aging treatment for 16 hours, the some rolling belts appeared recrystallization, and formed new grain.

Therefore, after heat treatment, the number and the intensity of the slip-able interfacial region would be reduced, and the corresponding interfacial relaxation effects would need a higher activation energy under the vibration load.
In fact, many kinds of interface relaxation effects (e.g. the relaxation effects of the grain boundary[19] and phase interface[20], the interface relaxation of the metal-matrix composites[21] and some viscoelastic polymer composites[22], etc) were manifested in peaks form in a suitable environment.

Polarized samples immersed in SBF at 37 °C for times ranging between 16 and 192 h showed the formation of HA crystals onto the negatively charged surface, starting from a number of isolated grains which subsequently merge in large aggregates.

To enhance the formability of the GA steel sheet, the previous works [1-5] focused on controlling several factors such as grain size, crystallographic orientation, temperature, coating thickness and phase composition of the intermetallic layer.
