In addition, the electrochemical results show that the TiO2 coatings significantly reduce the corrosion rate of Al substrates.
Before anodizing, the Al substrates were annealed at 500 °C for 3 h to remove the mechanical stress, cooled spontaneously.
SEM images of untreated Al (a), normal nano-TiO2 coatings (b), nano-TiO2 vacuum dip-coatings on Al with anodized pretreatment (c), partly damaged nano-TiO2 coatings (d) On the modified surface (Fig.1c, d), fig. 1c shows the vacuum dip-coated surfaces mostly become smooth and uniform, and few cracks are observed.

These findings are in agreement with Azlin et al [15] who reported that the porosity of the treated composite is inconstant as filler loading increased.
According to Elshereksi et al [16], the neat PMMA possessed slightly higher KIC properties than the PMMA composite.
At relatively low HA levels of up to 5 wt%, Chow et al [17] observed that the KIC of PMMA increased.
According to Fujishima et al and Zhao et al. [18, 19] respectively, the KIC for most DRCs range between 0.7 to 2.2 MPa.m1/2 depending on filler type, filler/matrix ratio, and testing method.
These findings are in agreement with Johnson et al [22] who observed that the KIC of the composite was reduced when the filler content was increased up to 44 wt%.

The flow stress of Al-Cu-Li-Mg-Ag alloy during hot deformation can be expressed by a Zener-Hollomon parameter in the hyperbolic-sine function with the hot deformation activation energy H∆ of 250.45kJ/mol.
Experimental Procedure The Al-4.0Cu-1.0Li-0.4Mg-0.4Ag alloy was prepared by melting and casting under argon atmosphere.
Results and Discussion The true stress-strain curves of Al-Cu-Li-Mg-Ag alloy during hot compression are given in Fig.1.

For, example, Jafari el al [6] conducted series tests to study the strength of concrete joint samples under normal stress of 4 MPa and shear velocities varying from 0.005-0.4mm/s, as well as different loading cycles.
Simlar works were also conducted by Jing et al, Homand et al, Hutson and Dowding, Lee et al and Plesha [7-11].
Based on the experimental works, Jafari el al and Jing et al [6-7] also primarily presented a constitutive relation of rock joint under dynamic cyclic loading condition.
