The DAD x-ray data for the as implanted samples is displayed in Figure 1.
Annealing the 5×1016 H2+ /cm 2 implanted sample at 900 °C leads first to a reduction in the strain and ultimately (for annealing times greater than about 45 minutes) the damping of the diffraction fringes and almost complete reduction of the strain.
Figure 5 contains the DAD x-ray data for both implant conditions after a multi-step annealing regime consisting of a 24 hour anneal at 500°C followed by annealing at 900°C for various times.
This shows that a significant reduction in the annealing time at 900 °C is required to produce blisters with a 500 °C anneal.

The ECU of engine was based on calibration data and the test bed without post-treatment devices.
With fuel properties, injection timing and pre-injection quantity respectively changed, in-cylinder pressure and emissions data were measured.
At the same injection timing, it can be found that the benefit of using butanol addition for the reduction of soot emissions is obvious.
The more the proportion of butanol in the blends is, the greater the overall reduction of soot emissions can be obtained.
With oxygenated addition, the oxygen atoms could enter rich fuel region and consume soot precursors through the formation of hydroxyl radicals, combined with the latent heat of vaporization of butanol is higher than diesel and the ignition delay of the combustion prolonged, result in reduction of soot emission.

Results and discussion
In Fig. 1(a) differential data are reported at selected temperatures and strain rates.
The data were normalised by means of AISI 316L m [7] for comparison.
The s’ values at different temperature against temperature are reported in Fig. 1(b), where the experimental data point at 1000°C with 10-5 s-1 is not reported, since dynamic recrystallisation occurred and the flow curve showed flow stress reduction with straining.
Experimental data sV/m vs. s’ and so/m vs. s’ are reported in Fig.s 2(a) and 2(b), respectively.
However, to author’s knowledge, there are no data available on s in commercial alloys like AISI 316L.

The machinability data systems are essential for the selection of optimum cutting conditions during process planning, and it has become an important component in the implementation of computer integrated systems.
· Data acquisition card set-up (DAS 1602/12)
There are several reasons for emphasizing the 2k design, such as a relatively few runs are required, the design is easy to use in sequential experimentation and the data can be processed using graphical methods.
The data collected is shown in Table 2. 5.
Analyzing the results The models are fitted to the data and graphs are generated to evaluate the effects of machining conditions on cutting forces, tool life and surface roughness.

The digitized data was used for development of Pro-E model.
Many lightweight materials have been used for vehicle weight reduction.
However, for the vehicle’s primary structure, carbon fiber composites offer the potential of great weight reduction without compromising structural integrity, crash worthiness and secondary processing operations.
The digitized data was used to visualize and develop Pro-E model, which was scaled up to generate CAD drawings for tool development.

The data are taken qualitatively for the crystal growth observation and quantitatively based on real-time temperature recording.
For each series of experiment, the measurements were repeated several times to obtain the cycling stability data of the PCM and the effect of ultrasound irradiation.
In other side, the suppression of phase separation effect in CaCl2.6H2O due to sonocrystallization treatment related to reduction of the solution’s metastable zone by the formed cavities and thus increasing the growth rate of the crystal [5].
The latter might be due to formation of cavities that lead to reduction of the solution’s metastable zone and thus increasing the growth rate of the crystal.

The continuous operating data in two years shows that Fe/Cu process can effectively improve the biodegradability of wastewater and enhanced the subsequent biological treatment.
Adding Cu expands the potential difference between the two poles, so the efficiency of electrochemical reaction is increased and the iron reduction capacity is improved.
Our research group studied on the reactivity of Fe/Cu bimetal system in transformation of refractory organic pollutants and particularly investigated the reduction with chlorinated aliphatic compounds[4], organic dyes[2,5] and nitro aromatic compounds[6-8].
Studies have found that this kind of material can be destroyed its chromophoric groups through reduction reaction and the biodegradability can be improved.
The continuous operating data in two years shows that the average removal rate of COD, BOD, total phosphorous (TP) and color was reached to 86%, 93%, 76% and 85%, respectively.

The increase in water molecules release and reduction of molecular oxygen release from the barium cerate, irradiated by high-energy ions is found during vacuum constant rate heating.
It is suggested that the partial reduction from В4+ to В3+ of the cations in the lattice B-sites takes place under irradiation due to formation of oxygen vacancies.
The state of the surface relief according to atomic-force microscopy data is also in agreement with the results of SEM.
Unfortunately, the adsorption band region of carbonate structures (1300-1600 cm-1) overlaps the region of OH group bending vibrations, complicating data interpretation.

Unless noted otherwise, the majority of the data reported in this review was generated on this or
similar microstructure.
Crack nucleation is then related to the magnitude of the fatigue parameter, often calibrated to smooth specimen data.
This life fit was developed using uniaxial data from [1] and is valid for lives between 3000 and 10 6 cycles including data with strain ratios ranging from R = -1 to 0.8.
The UTRC data shown in Fig. 4 corresponds to gross slip conditions.
Future Directions Compared to most material systems, there is a good amount of fretting fatigue data coupled with microstructure-based models for duplex Ti-6Al-4V.
