“…Second, asymmetric rolling of dissimilar sheet materials (e.g., Ti64 and Ti17) has been shown to be capable of producing solid-state bonds as a result of high, local shear strains which enhance mechanical intermixing and inter-diffusion. [264] VI. SUMMARY Current understanding of various aspects of the thermomechanical processing (TMP) of a/b titanium alloys have been summarized in terms of hot-deformation behavior and the evolution of microstructure, texture, and defects.…”

Current understanding of the principles underlying the thermomechanical processing (TMP) of a/b titanium alloys is reviewed. Attention is focused on the formulation of constitutive descriptions for plastic flow under hot-working conditions, the evolution of microstructure, the occurrence of defects, and novel/emerging TMP techniques. With regard to constitutive behavior, descriptions of the plastic flow of the individual phases and two-phase alloys per se are summarized. The important influence of phase morphology, size, and volume fraction on plastic flow is emphasized. Mechanisms which underlie microstructure evolution include beta recrystallization (in the high-temperature b field), the development of dislocation substructure and its effect on dynamic and static spheroidization of colony microstructures (in the two-phase field), static and dynamic coarsening of primary a, and the development of deformation and transformation textures. In the area of defects, the effect of TMP variables and starting microstructure on the formation of cavities, the persistence of microtexture, and the development of undesirably-coarse b grain structures are described. The current status of relatively new processing techniques for a/b titanium alloys such as low-temperature superplastic forming and solid-state joining (via linear friction or friction-stir methods) are also briefly reviewed. Last, R&D which could help to resolve deficiencies in the current knowledge base for TMP of a/b titanium alloys are summarized for each of the areas.

“…The most common method for welding rivets is frictional welding. However, in this method, because of high welding temperature, unwanted intermetallic phases may be formed, which could adversely affect the strength and corrosion resistance [ 6 ]. There are different methods for the welding of metals, such as friction, ultrasonic, laser and spark plasma welding (SPW) [ [7] , [8] , [9] , [10] , [11] ].…”

“…Being a generally melt-free technique, friction stir welding can enable a better control over the grain size. However, the peak temperature at and near the joint interface can be very high and lead to the formation of brittle intermetallic compounds or other defects, resulting in non-uniformity in the flow pattern, composition, and microstructure, especially if the beta transus temperature is surpassed [7]. In the case of titanium, friction stir welding requires particular care due to titanium alloys low thermal conductivity.…”

In the motorsport industry, the choice of material for manufacturing the heat resistant components often falls on titanium alloys. In most cases, the production flow for this kind of part involves CNC machining and subsequent assembly by welding process, to other parts obtained by cold plastic forming and possibly made using different titanium alloys. Hence, the alloying element-content in the joint area can be extremely heterogeneous and variable point-by-point. To investigate this topic further, dissimilar welding of the alpha/beta alloy Ti6Al4V and of the oxidation-resistant alpha alloy KS-Ti 1.2 ASN-EX was made by GTAW technology and using different filler metals. Chemical and mechanical properties of the welds were investigated by XRD, SEM-EDS, microhardness maps, and tensile and bending tests. Results show that, despite the different alloying elements present in the two filler wires investigated, static properties of the welds are similar. Results also show that the local V/Al content ratio affects the microhardness as it is responsible for the creation of supersaturated alpha phases during the cooling of the weld beads.
