When the average temperature exceeded phase alteration temperature of 1Cr11Ni2W2MoV, the original gray strip martensite structure was replaced by tempered sorbite structure, which caused a sharp reduction of the workpiece surface hardness.
The detected thermal emf was transferred into temperature readings based on the calibration data [6].

In the effect of laser alloying with powder of carbides occurs size reduction of microstructure as well as dispersion hardening through fused in but partially dissolved carbides and consolidation through enrichment of surface layer in alloying additions coming from dissolving carbides.
One can notice the area in the micro-hardness measurement data plots with the clearly lowered hardness, about 680 HV0.1.

The fresh and hardened voids of PC containing pumice fine were up to 9% greater than the PC without fine resulting in about 11% reduction in the hardened density of PC with fine.
The aggregates sieve analysis data can be seen in the below graph.

Aluminum die casting components are widely used in vehicle constructions because they satisfy the conflicting requirements between weight reduction and mechanical property improvement.
The scatter of the material data can be predicted by using the proposed method.

Additionally, implementation of these coatings based radiative cooling phenomena would be very effective in terms of reduction of global warming and heat island effect.
Here we compared the effective refractive indices of these composites from two approaches and suggested a possible utilization of these data to advance the DRC coating structures.
(a,b) Transmissivity data obtained for different thicknesses (in microns) at (a) fill fraction FF = 0.1, (b) FF = 0.3 , (c,d) calculated wavelength dependence of refractive index and average refractive indices from Method 2 The emissivity values of proposed composites can be further calculated from the transmission data.
Therefore, the data obtained from the transmission-based approach is expected to be the most suitable approach for further utilization in the Bragg stack designs.

Considering the improvement of the surgery quality and the reduction of health recovery time, surgical drill must be easy to drill through the bone with smaller thrust force.
Comparing with the datum of axial force and the theoretical model obtained by cortical bone drilling, the charters of both of them was consistent [3].
The change of drill's shape will cause a rapid reduction in drilling force and temperature.

To evaluate the length-to diameter ratio effect on quasi-static compression data, additional compression tests were conducted keeping the diameter constant, but with ratio of 3, 2.5, 1.6 and 1.2.
It was found that length-to-diameter ratio has no effect on the compression data.
The statistical area 4.37 mm2 is chosen for each specimen in order to gain the accurate data of the area fraction of twinned grain and twin lamella.
It is evident that m has a moderate but clear reduction with continued aging time.

In fact, two distinct logarithmic regimes have been reported for fitting crater depth data in femtosecond laser ablation of sapphire, semiconductors, and metals [8, 10, 11].
The ablation volume of the craters ablated by femtosecond laser pulses was calculated through the data of the AFM images.
The ablation efficiency reduction at high fluences was due to absorption of the laser pulse energy by the surface-induced air plasma and redeposition and resolidification by the strong recoil pressure exerted by the ambient air background, which was proposed by Grigoropoulus et al. from their time-resolved pump-and-probe images [8].
Measured volumes from AFM scanned data in Fig. 2. on different crystallographic facet planes.

Table 1 Input data for ASPEN PLUS Tray number 101 Type of condenser Total Type of reboiler Kettle Reflux ratio [wt %] 12.52 Flowrate of top product [kg/h] 10068 Feed location #41 Top pressure [kPa] 390 Pressure change [kPa] 100 Supercooling temperature of top reflux [°C] 200 In the distillation system, because the physical properties of each component are similar and there are no association phenomena in the vapor phase, the system can thus be expressed by state equations.
The input data for ASPEN PLUS are shown in Table 1.
Comparison between the simulation results and the actual industrial data is given in Table 2, which shows good agreement.
The optimization has resulted in a reduction in the utility requirement.
