Small grains start to form on the 10 min annealed thin film and become larger for the 20 minutes annealed film.
The number of the spot is observed to increase when the annealing time is increased.

Whereas surface hardness was indeed increased, large numbers of chromium nitrides were precipitated in the surface layer, which deteriorated the corrosion resistance of the steel.
The specimen was etched slightly with a solution of 5wt% (HCl:HNO3 = 1:3) in ethanol to reveal the austenitic grains of the steel substrate.

The high temperature processing results in increased crystallinity and grain size of HA phase leading to decreased solubility and resorption rate.
The cells could proliferate over the samples, because the number of attached cells significantly increases with time (p < 0.05).

Mining targets are divided into two general categories of materials: placer deposits, consisting of valuable minerals contained within river gravels, beach sands, and other unconsolidated materials; and lode deposits, where valuable minerals are found in veins, in layers, or in mineral grains generally distributed throughout a mass of actual rock.
In the mining sector hazard is a result of: · psychical and moral depreciation of the equipments and facilities (e. g. mechanized installations for exploitation, dragline excavators, equipment for perforation / drilling, ore transportation equipment, equipment for the production of compressed air and water drainage, ventilation installations, extraction installations, equipment for preparation plants, equipment for automation and dispatching) used in underground and surface mining; · lack of advanced equipment for the execution of preparation and opening works; · poor conditions health and safety at work (e.g. increased risk regarding safety of workers from stopes) and delays in the execution of investment for the commissioning of new capacities (with implications for the production capacity); · building abandoned to the mining areas, due to the reduction of production, the number of staff and space requirements, degradation of roads and access routes to the main and auxiliary buildings

Such as the main plants of arid environment—Populus euphratica Oliv. and Populus pruinosa Schrenk, they have strong root system to absorb water from deep and vast area of soil and their coarse roots and trunk tissue accumulate a large number of water, so they can adjust their daily water in drought conditions,At the same time, they can absorb a certain amount of soluble salts from soil, so they perform a strong drought-tolerant, salt-tolerant capability.

Eclipse itself is a frame platform, but supported by a number of plug-ins, Eclipse possesses the flexibility that is rarely found in IDE software with relatively fixed functions.
In addition, the added canvas, audio and video elements need to be coordinated by API to achieve the fine-grained control.

Introduction With the increase of mining depth, the number of coal bumps also showed a trend of increasing.
The false roof of No.5 coal seam made by mudstone had the thickness of 0.6m, thickness of immediate roof made by fine-grained sandstone was 7m, the upper roof was fine sandstone with the thickness of 10.4m, the immediate floor was mudstone and thickness was 2m, the old floor was silt-finestone.

To further suppresse C, N aggregate in the grain boundaries to form carbonitride chromium compound, usually molten steel was fed titanium wire in VOD refining process.
In the prerequisite of Ca / Al> 0.13% , By blowing hydrogen for flexible stirring before feeding titanium wire to discharge CaO·SiO2 and Al2O3·SiO2·CaO inclusions, the number of two-phase inclusion CaO·TiO2-MgO·A12O3 could be effectively reduced.

Steels obtained this way are always characterise by their martensitic-bainitic structure and the high strength properties are a result of wide refinement of grains, a high degree of cold working and very high density of dislocations, which have the effect of strain hardening [3,4].

Introduction The crystal structure is called anisotropic or textured when some fraction of the grains within a metallic structure is oriented in one or more preferred directions.
The calculated volume fractions of the main texture components were seen to be more unequivocal in describing the texture variation than maximal texture numbers.
