Specimens were heated to a soaking temperature that varied from 1100 to 1250 °C for 5 or 45 min and control cooled to 1000 °C in 6 min, where they were compressed to 40 pct reduction at a strain rate of 1.0 s-1.
Solubility product data are taken from Gladman [5].
A true strain of 0.5 was targeted during testing; however, slightly more deformation was achieved: 0.52 ± 0.02 true strain (40.7 ± 1.1 pct reduction).
The thermal simulations used were 45 min hold times at 1100, 1150, and 1200 °C, as well as a 5 min hold at 1200 and 1250 °C with a single-hit compression step added at 1000 °C for 40 pct reduction.

Compared to that of undamaged heat treated forged one, the tensile mechanical property of the repaired laser melting deposited sample got a few decrease but was still well, in which the tensile strength σb, yield strength σs, elongation δ5 and reduction of area Ψ was 1627Mpa, 1285Mpa, 10.5% and 45% respectively.
However, there is no relative data in the open literatures.
Compared to that of undamaged forged one, as shown in Table.1, the tensile mechanical property of the repaired sample got a few decrease but was still well, in which the ultimate tensile strength σb, yield strength σs, elongation δ5 and reduction of area Ψ was 1627Mpa, 1285Mpa, 10.5% and 45% respectively.

Vmin and Tmax have been observed at Umax, Fmin and FRmax, suggesting that the thermal effect is a dominant factor in determining the extent of reduction in the wear rate.
Data acquisition and processing were done with the Kratos Vision 2 program.
These circumstances suggest that in the parameter range studied the thermal effect is a dominant factor in determining the extent of reduction of the wear rate induced by the nitrogen PIII-treatment.
At the same time, Vmin and Tmax have been observed at Umax, Fmin and FRmax, suggesting that the thermal effect is a dominant factor in determining the extent of reduction in the wear rate.

In many research studies, one of the most promising methods for removing NO is selective catalytic reduction (SCR), in which catalysts are employed with reducing agents such as NH3 [1].
Manganese and Cerium compounds are also effective in selective catalytic reduction with NH3 [3, 4].
The data obtained are given in Table 1.

Due to an increasingly high requirements regarding energy saving, higher power machinery and emission reduction, a need for bearing weight reduction has arisen.
It is expected that once sufficient amount of test data is collected, it will be possible to correlate the inclusion depth, their minimum size and shape factors with the crack initiation process much easier than through conventional testing. 104 5μm 5μm 5μm 65 mm 250 mm 570 mm 106 5μm 5μm 5μm 110 mm 280 mm 445 mm 4.5 * 107 5μm 5μm 5μm 160 mm 280 mm 373 mm Figure 3 Cracks after one-point RCF testing (a) number of cycles = 104 (b) number of cycles = 106 and (c) number of cycles = 4.5 * 107.

Immersion and reduction process was repeated up to 4 times to thicken the thickness of gold plate surface.

The simple cantilever beam model appears to fit with Asaka’s model and supported by the measured displacement data.

The reduction in weight has been achieved through the use of thin-rimmed gears, which has underlined the query about the strength evaluation.
The increment of tooth-root stress that is characteristic for thin-rimmed gear and causes the reduction of fatigue life, has been well elaborated in the literature.

In these characterizations the calculated values from the area fractions, as well as the statistical treatment of obtained data were responsible to the quantitative of different properties.
According Fig. 1b the result of use is a reduction of these features and a correspondingly apparent sharpening of edges and other sharp details [12].
According Figure 1(b) the result of use is a reduction of these features and a correspondingly apparent sharpening of edges and other sharp details [12].

Yet there are no good quality randomized controlled trials investigating the efficacy of offloading interventions for pressure reduction and ulcer prevention amongst individuals with diabetes and neuropathy.
(Abbreviations: GRF, ground reaction force; %BW, percentage of body weight). [6] The use of cushioned insoles during running resulted in significant reductions in mean vertical ground reaction force peak impact and loading rate, as well as peak tibial acceleration.[7] Experimental setup The behavior study of composite structure insoles started to establish constructive variants (shape, size, material) and also the modality of exposure of these samples at different degrees of softening (time periods) in 5%saline concentration, in water and under negative temperature.
Results and conclusions Designed analysis allowed obtaining important data (size, color, structure) on the evolution of behavior subject to the effect of saline insoles (like human sweat) or just water and temperature variation respectively.

The weight reduction ratio of the laminate to the monolithic sheet of the same dimensions becomes 16.8, 12.0 and 9.3% when the skin thickness is 0.2, 0.4, and 0.6 mm, respectively.
Therefore, in this study, yield locus of the monolithic copper sheet was measured by biaxial tension test, and yield loci of the perforated core sheet and the laminate with 0.2 mm skins were determined by FE analysis using homogenization method based on the material data of the monolithic sheet.
Although its weight reduction, strength and formability are not sufficient enough at present, there is a possibility to design a useful laminate by improving strength and formability of skin material and optimizing perforation pattern of core layer.
