“…Titanium presents strength comparable to that of steel; this aspect combine with the low density makes it the structural metal with the highest specific strength being more efficient in terms of weight/volume ratio and, therefore, resulting in a lighter structural component compared to steel or the other light alloy such as aluminium and magnesium with similar mechanical strength (Lütjering and Williams, 2003). Moreover, the high strength combined with the low elastic modulus, half of that of steel, results in a superior toughness or modulus of resilience (Russell and Lee, 2005).…”

The fabrication of the workhorse Ti-6Al-4V alloy and of the Ti-3Al-2.5V alloy was studied considering the master alloy addition variant of the blending elemental approach conventionally used for titanium powder metallurgy. The powders were characterised by means thermal analysis and X-ray diffraction and shaped by means of uniaxial pressing. The microstructural evolution with the sintering temperature (900-1400ºC) was evaluated by SEM and EDS was used to study the composition. XRD patterns as well as the density by Archimedes method were also obtained. The results indicate that master alloy addition is a suitable way to fabricate well developed titanium alloy but also to produce alloy with the desired composition, not available commercially. Density of 4.3 g/cm 3 can be obtained where a temperature higher than 1200ºC is needed for the complete diffusion of the alloying elements. Flexural properties comparable to those specified for wrought Ti-6Al-4V medical devices are, generally, obtained.

“…Like many hard materials, they are quite refractory, yet unlike many ceramics, they have high thermal and electrical conductivities. In fact, the electrical conductivity of Ti metal is lower than that of its diboride [55][56]. Some of these, especially TiB 2 , also have considerable resistance to various forms of corrosion including attack from oxidation, liquid metals, and acids [55,[57][58].…”

“…The temperature at the contact point between tool and workpiece has been estimated anywhere from 700º to 1300ºC during machining due to friction and rapid shearing of the workpiece [13,56,106]. The high temperatures cause C from the diamond to diffuse into the steel chips and quickly dull the cutting edge.…”

In this paper, the effect of tool tilt angle on tensile-shear failure load and weld zone properties for 1050 aluminum plates, welded by friction stir lap welding, were investigated. For this purpose, tool tilt angle was varied from 0• to 5• under the constant other parameters, such as tool geometry, tool rotation speed of 1200 rpm and tool travel speed of 30 mm/min. The tensile-shear test was employed to test the mechanical properties of the joint. Optical microscope examinations, microhardness and temperature measurements were also performed in weld zone of lap joints. According to overall results, the tool tilt angle has a reasonable influence on the joint soundness and weld defect formation. If the tool axis was perpendicular to plate surface or a larger tool tilt angle was used, such configurations had harmful effect for the weld zone. In such case the tensile-shear failure load dropped from 4853 N to 2799 N. Recorded peak temperatures varied from 381• C to 438• C in the weld center. The measured mean hardness values of the stir and heat-affected zones were 31.5 HV and 28.3 HV, respectively, which are lower than that of aluminum 1050 base metal (40.7 HV).
