. % Cu (a - the number of particles; b – area occupied by the particles of a certain size By the methods of light microscopy it is showed that the casting with 0.08 wt. % copper content had the structure of ferrite and pearlite with graphite inclusions (Fig. 2 c).
Fig. 4 – Cupric inclusions in a grey cast iron alloyed with 14.4 wt. % Cu Fig. 5 – The influence of copper on the mechanical properties of gray cast iron (1 - Brinell hardness, 2 - Perlite microhardness) Because copper is practically insoluble in iron at ambient temperature, all the remaining copper in the iron-carbon alloys was precipitated in the ferrite grains or in a ferrite of pearlite in the form of nano-inclusions or inclusions of submicron size.

Typically, the numbers for ISO settings are stated as factors of 2, such as ISO 100, ISO 200 and ISO 400 which can be up to ISO 204800 (Nikon D4 and Canon EOS-1DX, both released in 2012).
It is like getting grains when using high-speed films.

This high-speed vibration causes what is termed gigacycle fatigue in which cycle numbers exceed 109.
This steel had a tempered martensitic microstructure with a prior austenite grain size of 30 µm.

A large number of investigations on quasi-static stress-strain responses for titanium alloys have been reported [1-8].
Metallographic examination of the aging rod reveals that the microstructure of material is duplex microstructure, containing lamellae Widmanstatten structure dispersed between these primary globular α grains shown in Fig. 1.

The design of various optical interference coatings, such as antireflection, high-reflecting dielectric mirrors, band-pass and edge filters, is established on the basis of appropriate choice of refractive index, layer thickness and the number of layers.
When the concentration of Ge substituent reaches a critical level, these strong localized elastic-strain fields develop into chains of overlapping strain fields, which can pass through the entire crystalline grain.

It has reported that higher coating thickness increased the grain size and the roughness of the coating [4].
By moving faster, the number of sputtered atom that deposited on a the substrate surface also reduced.

The factor number of test was 5 and level figure was 7, test factors and levels of U7 (75) uniform design table were chosen according to test requirements in table1, and uniform test scheme and experimental results were listed in table 2.
The results showed that particle shape of sample 2, 6, and 7 was irregular, particle surface adsorbed grains with only about 5nm , and had a certain degree of particle reunion.

When describing the stripping inflection point, it is the number of passes at which the deformation of the sample is the result of moisture damage and not rutting alone.

Note that due to the crystal and sample symmetry (Bunge [4]), each of these components appears a number of times in the ODF.
Indeed, the Taylor model does not take the heterogeneity of plastic strain inside the grains into account, and ALAMEL does it only in a limited way.

For instance, the number of circuits required in wiring bundles is increasing due to the diversification of electronics.
This aging can reduce the composite performance by the metallurgical transformations which can occur: recrystallization, grain growth and/or formation of brittle intermetallic layers between both metals.
