As there is a need for the weld configuration of Ti3Al2.5V alloy to Ti6Al4V-ELI alloy, coupons were made accordingly.

For titanium and titanium alloys produced using PM routes, most of the early data on fracture toughness were published by Eylon et al. and Donachie et al. during the late 1990s [6, 24].
Most recently, El-Soudani et al. have carried out detailed work on the optimisation of extrusions for aerospace applications deriving from blended elemental powder based Ti-6Al-4V [42].
During 1970s and early 1980s Conrad et al
El-Soudani et al. had measured the fracture toughness of blended elemental powder based Ti-6Al-4V extrusions containing a range of oxygen and hydrogen contents, but this study does not show any trends because of non-systematic range of both interstitial elements [42].

Fraser et al [4] studied the variation of some physical properties of fababeans at four moisture contents of 10.3, 14.5, 19.5 and 25.0% wet basis.
However, Oyekan et al.[6] observed that if the cowpea got completely dried, the percentage of losses will be high during the threshing operation.
Usually, for any material to flow freely down an individual plane, the angle of inclination of the plane to the horizontal must be at least about 10 o above the angle of repose of the material Oyekan et al. [6].
This agrees with, Oyekan et al. [6] that some varieties have higher seed hardness which affects mechanical properties of cowpea during threshing.

Alauddin et al. [3] experimentally investigated the influence of machining conditions on the average cutting forces in the end milling of Inconel 718 under dry conditions using uncoated carbide inserts.
Lorentzon et al. [4] observed from turning experiments under dry cutting conditions that when machining alloy 718 at lower cutting speeds (below 50 m/min), the chip produced is long and continuous.
Recently, Devillez et al. [8] presented the results of surface integrity and cutting forces in turning Inconel 718 alloy under wet and dry conditions.
The miracle coating consists of (Al, Ti) N and has high strength to the substrate and good heat and oxidation resistance to enhance the tool life when machining hardened work-piece.

It also agrees well with the report of Zhao et al. [8, 9] about the TiO2/RB process.
The peak wavelength of MO aqueous solution clearly blue–shifted to the shorter range and simultaneously broaden under visible light irradiation, which is caused by N-demethylation according with the study reported by Zhu et al. [10], Han et al. [11] and Zhu et al. [12].

Claer et al. [5] studied on fatigue models for sandwich beams under both single-step and multi-step loading.
Mahi et. al. [8] studied on cyclic fatigue of sandwich composite beams under three-point bending.
Kanny et al. [10] studied on different loading frequencies on the sandwich beams with foam core.
Belouettar, Abbadi et. al. [11] studied on fatigue behaviour of composite honeycomb materials under four point loading.

Aatola and al. [2] conducted a comparative study between several vibration analysis methods.
In work of Bouzouane and al. [3] two types of wavelets have been tested on real cases: Daubechies and Morlet.
Djebala and al. [5] proposed an approach that benefits the local nature of wavelet analysis and its ability to detect transients.
Parey and al. [6] using empirical mode decomposition (EMD) used as a processing tool for non-stationary and nonlinear signals.

Song et al [10] reported orrosion behaviour of magnesium in ethylene glycol and found that corrosion rate of magnesium decreased with increasing concentration of ethylene glycol.
E.N.ElSawy et al [11] studied the effect of nitrates on corrosion of Mg and two Mg-based alloys (AS31 and AZ91) in presence and absence of buffers (phosphate and borate) of pH 8.
The objective of this study was to determine the buffer borate capacity and pH affect the corrosion behaviou of Mg-7.3 Al alloy.
