One of the most outstanding features of the alloy is its cold formability, such as cold rolling reductions in excess of 90% after solution treated[3].
The data in Table 1 suggests that the present operation parameters carried out in the TIG process, together with the AA or ST+AA treatment, are satisfactory to enhance the industrial application of the Ti-15-3 alloy.

To data, FESEM and TEM analysis are the most used and direct methods to characterize the percentage of the exposed {001} facets.
However, as the percentage of the exposed {001} facets further increased, the reduction of the diffraction intensity may be ascribed to the not very perfect crystal structure.

Because of the reduction in force transfer between fibers and the resin, the mechanical properties of the FRP reinforcements would be reduced.
Verification of the Model The numerical model prepared using ANSYS Workbench is verified from the data of full-scale fire tests conducted on six RC beams strengthened with CFRP sheets, which were protected with different insulation materials conducted by Firmo et al. [21].

Analysis on development trend of automobile material
1)Lightweight and environmental protection is the main development direction of the car material
2)Proportion of various materials in automotive applications is changing, mainly high-strength steel, ultra-high strength steels, aluminium alloys and magnesium alloys and other materials of a very large increase in usage, and cast iron, low-strength steel of gradual reduction in the proportion.
3)The combination will be more close between lightweight materials technology and automotive product design and manufacturing processes, and the car body structure material would be much material design direction.
4) Pay more attention to car material recovery technology
5) Electric cars, alternative fuel automobile special materials and auto function material development and application will be strengthened.

The Ti-5Al-5Mo-5V-3Cr-X alloys have a static strength of as high as 1,350 MPa and a percentage reduction in area of >20% under the solid-solution and aging state; therefore, they are high-strength and high-toughness titanium alloys.
During the experiment, the test under each strain rate should be repeated at least three times in order to enhance the credibility of the data.

Particle size of the raw materials was determined by laser analyzer or acquired from technical data sheets.
Refractoriness and refractoriness under load of mixtures with fly ash (FA-1, FA-2) was lower than of mixtures with reactive alumina (AL-1, AL-2) due to the higher content of flux oxides in fly ash mixtures which affect the refractory properties, however, the reduction was only by a maximum of 5 %.

The character of solid lubricants which can reduce friction leading to reduction in adhesive wearis outstanding.
The surface hardness and elastic modulus can then be evaluated from such load-displacement curve through appropriate data analysis[10,11].The UMIS II Instruments Criso, Australia tester with diamond Berkovich indenter was used.The tests were performed to the maximum load of 30 mN to avoid the substrate effect on the coating properties.

It is worth mentioning that the response times obtained at low voltages were not taken into consideration due to the limitation on the frequency of data collection in the measurement system.
The bias voltage dependence of the photocurrent increase has been reported for other material systems, and this can be attributed to the increase in carrier drift velocity and reduction of the carriers’ transit time as, t = l2/(µ.Vds), where l is the device length, µ is the carrier mobility, and Vds is the bias voltage [17, 18].
