The microstructure after flow forming reveals elongated grains in the direction of flow and the breaking up of the secondary phases in the microstructure.

The emissivity depends on a number of things such as spectral range, surface conditions, and temperature, etc.
This plastic deformation results in tearing off of the grains of carbide from deforming cobalt layers.

However, when the temperature of annealing reached 1280℃, the typical three-way type of a b c overburning phenomenon can be observed clearly in the grain boundary.
After a large number of analyses about the simulation data, temperature situation of P3 point is shown in Fig.6.

Analyses of samples chemical and structural composition were realised using a scanning electron microscope Jeol JSM 7000F with an Oxford Instruments EDX analytical unit with autoemission nozzle and a microanalysis unit INCA Energy 250 allowing element analysis from atomic number 5.
Ferrite forms polyedric grains, constituting approximately 50 % of structure.

A number of transparent conducting oxide materials have a large area of applications in industry.
The results indicated that high temperature annealing leaded to the films with a lower sheet resistance, which inferred a better crystallinity of films and lower defect near the grain boundary .The decrease in resistivity with temperature can be attributed to the increase of carrier mobility and the decrease of boundary scatter.

Titanium and molybdenum were added to refine the grains.
And with the increase of number and size on bulk martensite, the strength of the steel became strengthening.

Introduction Superfine sand refers to the fineness modulus of 0.7-1.5, the average particle size is under 0.25 mm, it’s poor grain size distribution, large void ratio, big specific surface area, high silt content.
