The results show that the surface of the obtained pure aluminum coatings is acicular, while blocks Al-Mn compounds phase exists in Al-Mn alloys layer, and the Al-Mn alloy layer is composed of Al, FeAl3, Fe2Al5 and MnAl6 phases.
Conclusions The Al-2%wtMn, Al-9%wtMn and Al-13%wtMn alloy coatings were prepared on low carbon steel by HAD treatment.
The surface of the obtained pure aluminum coatings is acicular, while blocks Al-Mn compounds phase exists in Al-Mn alloys layer, and the Al-Mn alloy layer is composed of Al, FeAl3, Fe2Al5 and MnAl6 phases.

Chen et.al reported (102) peak as the preferred orientation for the films prepared on solvo thermal chemical reaction [7].
However Nair et.al reported the (311) peak as the preferred orientation for the films prepared by chemical method [5].
A similar behavior was reported by El-Zahed et al. [10] in the Cu9Ge11Te80 films grown by melt quenching technique.

The effect of FRP reinforcement on the function of concrete bridge deck slabs was investigated by El-Gamal et al[12] through testing four full-scale restrained concrete bridge deck slabs, and it was found that compressive membrane action, which is similar to the mechanics scheme of arching action in curved shells was often exhibited in laterally restrained slabs.

Mustafi et al. [7] found that soda lime silicate can modification behaviour and porcelain stoneware tile.
In another study, El-Shimy et al. [8] found that soda lime silicate can reduce energy consumption and CO2 emission .
These result reflect those of El-Shimy et al. [8] who found that, more glassy phase will accompanied with dilation of closed pores and expansion due to entrapment of release gases mainly CO2 which turn increase water absorption in Figure 2(b).

Tc = 584 0C, YS = 280MPa, TS = 360MPa, El = 32% 2.
Tc = 6400C, YS = 260MPa, TS = 325MPa, El = 39% The microstructure of steel at low and high Tc is characterized by an equal axis ferrite grain with the sizes of (20-30) µm.
Chemical composition of IF steel are as follows (ppm): 1) - C-6, Si-22, Mn-100, S-8б, P-11, Cr-40, Ni-20, Cu-20, Al-36, N-6 and Ti-57 or describe in atom%: C2 Si3 Mn7 S P Cr3 Ni Cu Al5 N2 Ti5 Fe7121 2) - C-8, Si-13, Mn-140, S-90, P-17, Cr-50, Ni-20, Cu-30, Al-42, N-4 and Ti-94 or describe in atom%: C3 Si2 Mn10 S P2 Cr4 Ni Cu2 Al6 N i8 Fe 7121.
The ratios of Mn/S, Al/Si and Si/C are different between steels 1 and 2: 2.3 and 5.0, 1.7 and 3.0, 1.5 and 0.67 respectively.
Production condition and mechanical properties are as follows: steel 1 - hot rolling (TFR = 9000C, Tc = 690 0C), cold rolling (ε = 65 and 75%) on the thickness 1mm, annealing in the bell-type furnace at 7300C, YS = 160 MPa, TS = 310 MPa, El = 45%, Er. 11.5 mm; steel 2 - hot rolling (TFR = 9000C, Tc = 6900C), cold rolling (ε =70, 75, 80, 84 %) on the thickness 0.8mm, annealing (bell-type furnace) at 730 0C, YS = 160 MPa, TS = 310 MPa, El = 41.5%, Er.10.8mm.

Dynamic Analysis According to the above selection wave principle, El-centro wave, Tianjin wave, Shanghai artificial wave are taken.
In this paper, Newmark-β method is taken for dynamic analysis of cold-formed steel structure, to calculate the response of structure under El-centro wave, Tianjin wave, Shanghai artificial wave.
Fig. 6 The maximum displacement dynamic curves of structure under El-centro wave Fig. 7 The maximum displacement dynamic curves of structure under Tianjin wave Fig. 8 The maximum displacement dynamic curves of structure under Shanghai artificial wave Conclusions Modal analysis shows that each vibration modal frequency is gradually increasing and vibration period is reducing accordingly.
Dynamic analysis results show that the maximum displacement occurs in the same direction when the structure under the effect of same direction of El-centro wave, Tianjin wave, Shanghai artificial wave.

In literature [4], a Fourier series function was used by Xiaoping Pang, et. al. to represent the general film geometry of the bearing in circumferential direction.
For example, Leung et. al.[5] first examined a bearing having a spherical shape but their treatment showed that its behavior was similar to that of a comparable cylindrical bearing.
On the other hand, the results obtained by El Gamal[6] in his analysis for a symmetrical wedge shaped bearing, showed that for small wedge angle the bearing was found superior to the plain cylindrical one.

Mechanical Testing was carried to evaluate Ultimate Tensile Strength (UTS), 0.2% Yield Strength (YS), % Elongation (%El.), % Reduction in area (%RA) and hardness.
Contrepois et al [12] who studied the effect of rate of heating to aging temperature on α precipitation in Ti-5553, reported similar observations.
A selected set of SA and DA treatments based on studied by Santhosh et al [2, 9] have been used in this investigation.
However, studies by Wu et al [13] indicated that heating rates as high as 10 oC/min can influence the precipitate density in this alloy.
