On the basis of the hot compression data, critical stress (strain) or peak stress (strain) were determined with the assistance of the strain hardening rate versus stress curves.
The reduction in height is 60% at the end of the compression tests.
DRX volume fraction X is often calculated in terms of the data from the strain-stress curves and can be expressed as [10]: (3) where sp is the peak stress, ss is the steady state stress and s is the specific stress from flow curves.
(3) The kinetics models were developed to describe the evolution of DRX based on the stress–strain data, and the typical model at 923 K and 0.1 s-1 was expressed as (e < ec) (e ≥ ec) Acknowledgments The present work was supported by Ministry of Education of Guangdong Province University-industry Cooperation Project (No.2012B091100038), University-industry Cooperation Project of Guangzhou (No.7411447290986) and the PhD start-up fund of Guangzhou Research Institute of Non-ferrous Metals (No.2012B001).

The enhancement effect of pile-base post-grouting was analyzed through the comparison static loading tests and summarization of literature data.
Fig. 1 shows the discreteness of pile test data, reflects the control level of the bored pile construction technology.
Whereas, the load- displacement gradient data of pile-base post grouting piles is more discrete.
The shaft resistance reduction effect caused by the upward of pile, and the delay of the enhancement effect of tip resistance have led to the phenomenon that the stiffness of pile-base post-grouting pile below the general bored pile at the low load level.

However, the great reduction of crafting window brings challenges to the soldering quality and also poses higher requirement for the stability and reliability of lead-free soldering equipment.
A variety of performance boost testing methods need researching and exploring together with data accumulating in order to shorten the setup time from exploring to producing[1].
According to the statistic data, there are more than 100 kinds of lead-free solders manufactured all over the world like solder paste, solder wire, welding stick, etc.

At that the main objectives of the research were reduction of the labor coefficient of work relating to the preparation of surfaces of metal building structures, by applying the rust painting method, and creation of anticorrosive materials with universal properties combining the functions of rust, primer and basic coating modifiers.
Analysis of the data in table 2, allows to draw the following conclusions: • coatings with compounds AKS-K and AKS-B protect the clean steel surface to the same extent as the standard coating systems.
The analysis of the graphical display of the data obtained gives interesting conclusions, if we take into account the criteria of the quality of coatings proposed by M.

As a general rule, data accuracy
is reduced with increased punch speed.
In general, they require as input sheet thickness and material data.
Punch-Load data.
Press data and experimental conditions are summarized in Table 3.
As it can be seen, experimental data are affected by some noise.

According to the element analysis data, the least soluble fraction had the highest molybdenum content (Table 1).
Based on the element analysis data, the relative molecular weight of the elementary unit of this fraction was calculated.
The respective data are shown in Table 2.
This fragment size was calculated from the data of X-ray structural analysis of molybdenyl bis(acetylacetonate) [9].
As seen from the element analysis data, the compositions of these fractions did not virtually change after purification (Table 4).
