UV-Vis analysis indicated that the incorporation of Fe and varied calcination temperature may affect the optical properties as the absorption profile was shifted from 445 nm to 585 nm.
The effects of calcination temperature towards Fe-TiO2 properties are investigated and discussed.
Optical properties of samples were measured on a Shimadzu UV-VIS spectrometer (UV-1800) in the wavelength of 300-800 nm.
Another factor that can enhance the optical properties in visible light is by incorporating TiO2 with other metal ions [17,21].
The effect of calcination temperature on phase, morphology and optical properties were investigated.

In this paper, firstly, we give a brief introduction of the amorphous alloy material properties and compare the no-load characteristic of the AMMT with the SSMT.
Compared to silicon, the amorphous alloy material has the following characteristics: The amorphous alloy core is thin, the thickness is just 20 to 30μm, the fill factor is low; The amorphous alloy core has low saturation flux density; The amorphous alloy is five times firm than silicon steel; The amorphous alloy core’s material is very sensitive to mechanical stress and affects its magnetic properties [1].

Introduction Carbide, nitride and carbonitride precipitates can considerably affect the structure and properties of steels.
The level and character of their effect are determined by the state of precipitate ensemble forming at ingot crystallization and its further thermal and thermo-mechanical treatment.
This is a serious drawback, as in some cases these two factors can appreciably affect the kinetics of precipitates evolution.
The Choice of Calculation Parameters According to the above-presented algorithm for the description of thermodynamic properties of a system, one must fit a thermodynamic description of the free energy of Fe-V-Nb-C-N system based on the CALPHAD-method, so that it would be possible to calculate partial Gibbs energies from formulas (9) – (12).
The initial PSD of “NbC” particles practically does not affect the evolution of “VN” precipitates, but on the contrary, the kinetics of “NbC” dissolution is affected, though not too much, by the initial PSD of “VN” precipitates.

This paper reports cationic polymerization of Thevetia peruviana seed oil with styrene and divinylbenzene using modified boron trifluoride etherate as initiator, and the tensile strength, impact strength, moduli, elongation at break, hardness, and dynamic mechanical properties of the cured resins. 2.
Figure 6 shows the tensile properties and profile of ultimate tensile strength of TPO polymers, respectively.
The TPO polymers produced were observed to have good properties, with polymer 1 having overall best properties that make it a potential matrix material for composite development for industrial applications.

The environmental factors that can affect the materials corrosion behaviour such as temperature, dissolved oxygen, pressure changed compared with the shallow sea [5], and the materials corrosion behaviour was also different.
Many types of commercial aluminum anodes, performed good electrochemical property in shallow sea, suffered serious local corrosion and failed early in deepwater environment.
When the crystal size is refined, the anode mechanical loss during dissolution is reduced and the pits formed on the anode surface are easily to connect together, and the anode dissolution morphology is uniform.

Alloying with Mn or Ni has a strong influence on the electronic configuration and magnetic properties of the austenite and therefore on the SFE.
Their excellent mechanical properties have been a matter of study, and their relation with SFE is a key factor.
In general, alloying with Mn or Ni as has a strong influence on the electronic configuration and magnetic properties of the austenite and affects as well the influence of the interstitial elements on SFE.

A quantitative metallography study was conducted on the partially softened structure to investigate the number density of recrystallized grains and to verify the indirect measurements of the fraction recrystallized calculated based on the mechanical properties.

Excellent agreement was observed between the fraction recrystallized calculated from the mechanical testing data and estimated from the quantitative metallography results.
In addition to solute depletion, resistivity measurements can also be affected by dislocation scattering [9,11,12].

The effectiveness of envelope thermal properties affects the heating and cooling loads directly, therefore, it is important to select suitable technologies to improve the envelope thermal properties, making buildings more comfortable and reducing utilization of auxiliaryenergy consumption equipments by reducing the amount of heat escaping in winter and entering in summer.
Beijing: China Architecture and Building Press. 2011. ].Besides, Composite Light-weight (CL) building system, finish materials, and pasting insulation panels (such as expansion perlite panels, expanded polystyrene, extruded polystyrene panels, etc.), inside external walls are widely used technologies. 2.2 Doors and windows The thermal performance of windows has been considered the worst among all the envelope components, and has been one of the main factors influencing indoor thermal environment quality and building energy consumption.
Energy saving technologies of building services and equipment Building energy consumption, which is expressed in the form of electricity and fuel energy consumed by different facilities, and facilities conversion efficiency directly affects the fuel and electricity consumption.
For example, intermittent heating and cooling, selection of heating radiator and priority selection of natural ventilation to mechanical ventilation, etc. are the important considerations in the HVAC system design process[[] The Leadership Institute of Ministry of Construction.Practical engineering technologies in building energy efficiency.Beijing: China Electric Power Press.2008. ].

Similarly, other problems may be very sensitive to inaccurate assumptions in material properties, loading, geometrical idealisations etc.
In practice, however, the sub-modelling approach cannot be used in cases where the local non-linear response of the sub-model, not included in the global model, even mildly affects the global model response, as for tubular frameworks.
Using SK tm ==1σ (3) y LP P S σ= (4) y L m P P σ σ =∞= (5) where Kt and S are the elastic stress concentration factor and nominal stress, respectively, P is the load applied to the structure and PL is the structure limit load for elastic-perfectly-plastic material behaviour with a yield stress σy. σy/PL is independent of the material properties and depends only on the geometry and loading mode.

For dynamic or time-dependent studies, where non-linear behaviour, e.g. of connections, may affect structural damping or stiffness, or fatigue damage accumulation, the ability to incorporate such non-linearities into simplified global models is clearly important.

Similar to LED substrates, the near lattice-match to GaN and the high thermal conductivity are key properties [2].
It is suspected that this is a measurement artifact due to changes in external factors affecting the measurement unit (e.g., temperature fluctuations in the laboratory).
