An ASTAR system was used for ACOM diffraction data acquisition.
No data on the effect of ECAP on the activation energy are available but the present results show that ECAP reduces the activation energy of the whole precipitation process of q’.
A secondary precipitation was observed after ECAP and heating due to a reduction in the activation energy by the high density of defects created.

The diffraction peaks were assigned according to the
diffraction data of standard compound (JCPDS 34-0122).
This receding of the plume towards the target is due to a rapid thermalization of the KLN ablated species as a result of a reduction in their mean free path and the activity of KLN particles will decrease due to the collision with oxygen molecules.
This factor can be calculated using the following relation [12]: () [] ∑ = )(0)( )(0)( )( 1 hkl hkl hkl hkk hkl IIN II TC (1) where TC(h k l) is the texture coefficient of the (h k l) plane, I(h k l) is the measured intensity of (h k l) plane, I0(h k l) is the corresponding recorded intensity in JCPDS data file and N is the number of preferred growth directions.
The result is consistent with the Raman data in the previous paper [8].

A piece of slab (50x100mm) was cold rolled to 60 % reduction in thickness in a
laboratory rolling mill. 4x4 mm sample coupons were cut from this cold rolled steel.
The complete data obtained for the samples recrystallized at 750, 800 and 900 0C is presented in Fig. 3.
The data is presented in Table 1.
The slope of the linear fit to data is equal to Q/R and "Q" is calculated using the known value of gas constant R (8.34 J/mol).

Magnesium and its alloys
are attractive for use in lightweight constructions because of their ratio of strength and density which
may allow a significant weight reduction for structures.
These data help to develop a phenomenological yield condition, which can be used to describe the deformation of a textured polycrystal without modeling its microstructure in detail and thus extend the modeling potential to structural assessment and process simulations.
Fig. 1 shows the numerically obtained stress-strain curves for seven different orientations of a single crystal in the channel die experiment in comparison with the experimental data [1].
Hosfords support while providing the raw data of his pioneering experimental work on pure magnesium reported in [1].

However, in most of these methods there is usually a limit of the grain size refinement degree which can be obtained by a single SPD method, because at a certain level of strain, further grain size reduction cannot be achieved [8].
The experimental data, when plotted on σy – d-1/2 coordinates, usually exhibit a significant scatter which has been attributed to ‘second-order’ effects such as the influence of the grain size distribution [13,14] and/or the variable properties of the grain boundaries, i.e. their various diffusivity [15] or misorientation angle distribution [12,16].
Comparing these results with the data for aluminium alloy 5083 (with a higher density of impurities of Fe, Si, Cr) one can say that for AA5483 it is possible to obtain higher values of yield strength-strain coefficient.
(a) The Hall-Petch relationship, (b) evolution of Yield Strength as a function of strain values: data also include values for 5083 AA from Topping et al. [17], Newbery et al. [18], Horita et al. [19] and Hirata et al. [20].

Design Procedure The design of a fixed bed adsorber for a gas or liquid purification involves choosing the adsorbent and particle size, selecting an approximate velocity to obtain the bed area, and then determining the bed length for a given cycle time or calculating the breakthrough time for a chosen length. [10] The data used in carrying out the design was taken from a previous work carried out on activated carbon from palm kernel shell under the guidance of the senior authors. [11] The study established that palm kernel shell has high potentials for use in the production of activated carbon for sorption of metals from aqueous solutions.
AF A C C The template contained a first section in which data necessary for the various calculations were used as inputs into the relevant cells.
At the higher flow rate, the contact time of waste water with activated carbon was very short causing a reduction in the efficiency of removal of heavy metals.

This is consistent with the data on the swelling index, where the KOH solvent can cause excess carbon loss which will collapse the pore walls, lose porosity, and reduce the specific surface area.
The KOH solvent causes excess carbon loss, leading to the collapse of the pore walls and structural integrity, loss of porosity, as well as reduction in the specific surface area, water absorption capacity, and swelling index.

The alloy ingots were homogenized at 900 °C
for 48 h in a vacuum, cold-rolled to 50% reduction in thickness and then spark-cut into specimen
strips.
The volume fraction was determined by applying the lattice constants of the stress-aged and free-aged specimens measured by an X-ray analysis to the experimental data on the dependence of the lattice constant on the Be concentration in the literature [5].
All the data points fall on a single straight line.
