In the present paper, thermodynamic and kinetic simulations were carried out and correlated to these data, especially in terms of Si effect on M3C carbide precipitation.
A particularly successful modification proved to be the reduction of Si content from the usual 1.0 %Si to 0.3 %Si [2-4].
The carbon profile shows a strong dependency of the silicon contents at the interface, being the diffusion faster with the reduction of Si concentration at the interface.

Cutting force and Surface roughness data are
presented.
Cutting force data are transmitted to a computer with an acquisition board.
According to Eq. (1), increment of shear angle causes the reduction of shear force, however, the increase of chip inertia force based on Eq. (2).

The prediction of pitting corrosion-induced structural performance degradation is limited by the inspection means and experimental data.
Fig. 1 shows the process of chloride-induced reduction of steel diameter.
Besides, Fig. 7 shows that the proportion of longitudinal coordinate in Fig. 4 is not uniform, and all data are close to the line, which indicates that the logarithm of the pit depth do not reject the normal distribution.

These properties are typically characterized by data that relate to specific testing methods.
These multiple regressions were established using workability data determined shortly after the end of mixing (10 minutes of age).
On the other hand and for a given slump flow, an increase in the difference between slump flow and J-Ring values can lead to a reduction in filling capacity resulting from some lack in the restricted deformability across closely spaced obstacles (Fig 3).

Langmuir and Freundlich isotherms were used to analyze the equilibrium data at different temperatures.
Cross-linked chitosan shows a reduction of the band at 1600 cm−1, which may be related to the consumption of NH2 groups by glutaraldehyde, as a result of the cross-linking process (via formation of Schiff’s base, RCH NR).
However, the experimental data were measured at 48 h to make sure that full equilibrium was attained.

Spectral data confirmed commonly the characteristic absorption of substituted groups and aromatic segments in molecular structures.
As for Sal-Azo and Sal-Me-Azo with phenyl substituted group, it is obviously observed that trans isomer converted to cis isomer as proved from the reduction of the strong peak at 364 nm and the concurrent weak enhancement of the weak peak at 452 nm.
The present data suggested the phenyl/naphthyl substituted group can effectively influence the conjugated structure and aggregate mode, and subsequently regulate the relative ratio of isomerization.

Based on the survey data collected from 208 farm households of Zhili, Balidian, Huanzhu and Baique, 4 towns of Wuxing district of Huzhou city in Taihu Basin, this paper quantitatively analyzed the influencing factors on farm household’s adoption behavior of soil testing and formula fertilizing technology (STFFT) by using Logit Model.
It covered almost all the agricultural counties, with more than 7 million tons of irrational fertilization and 6%-30% of N and P loss reduction, it has a significant result for controlling ANPSP [4].

An imaging system based on the transmission and reflection modes in the terahertz (THz) region is developed by using a backward-wave oscillator (BWO) as source, a Golay-Cell as detector, and an oscilloscope as data acquisition unit.
The system software based on the oscilloscope is designed to control the object movement, and the capture and display of the continuous THz wave image data.
The data form the Local Area Network (LAN) of oscilloscope (Agilent DSO5052A) are acquired and stored by computer.
The automatic control process and data recorded by the oscilloscope are controlled by software designed for the imaging system.
The software is mainly composed of three modules, including the platform operation control module, the serial data processing module based on the Electronic Industry Association-Recommended standard-232 (RS-232), and the LAN interface data acquisition module.

The experiments were repeated at least three times in
the same conditions in order to achieve a statistical distribution of the acquired data: such data are
then used as a reference for the 2009 edition of the extrusion benchmark.
The third step is the comparison of the results: during the conference the hidden results of the experiment are disclosed and the different FEM codes predictions are compared to the experimental data, thus providing an interesting evaluation of codes capabilities.
In this direction, for example, the software houses can promote their codes capabilities on the basis of scientific and well monitored experimental data, the industrial users can verify their ability to properly perform a simulation with their own code or even select a code among those participating the contest.
Fig. 2: Thermocouple position The billets were heated up to 450 °C in a furnace, with the billet surface decreasing to 432 °C just before extrusion: the billet temperature reduction was caused by the billet loading procedure that took about 1 minute.
It is worth noting that the curve of the velocitymeter of the bottom profile showed a lower scatter distribution of the data compared to the other curve, this being in relation with the velocitymeter models: the velocitymeter used on the top profile is older than that used on the bottom, thus producing a worse filtering of acquired data.

The paper discusses strategies for obtaining the lowest cost grain refiner addition and
provides an explanation for how the refinement of equiaxed grains leads to a reduction in hot tear
susceptibility.
Introduction Optimisation of grain refinement and reduction of hot tear susceptibility of alloys are key factors that need to be considered in the production of metal castings, whether they be continuous cast billet, ingot or shape castings.
However, if the grain morphology is spherical then a reduction in grain size may in fact increase the hot tear susceptibility of an alloy.
