“…Titanium has excellent corrosion resistance, creep, and fatigue properties, and a high strength-to-weight ratio [ 1 , 2 , 3 , 4 , 5 ]. Titanium and its alloys have several advantages and, therefore, have been recognized as potential materials for applications in the automotive, biomedical, and aerospace industries [ 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 ]. However, titanium is expensive, and—when manufacturing aerospace parts, in particular—after the conventional machining process, up to 90% of the material is discarded as chips.…”

A one-step hybrid bending/diffusion bonding process (HB/DBP) was developed for application to Ti-6Al-4V sheets to effectively improve buy-to-fly (BTF) ratio of aircraft parts, integrating sequential diffusion bonding followed by a bending process. The resulting bonding characteristics of these titanium alloy sheets were analyzed. Microstructural analysis and mechanical lap shear tests were performed to estimate the bonding quality. Additionally, bonding ratio, thickness strain, and shear strength were evaluated in relation to pressure under increasing temperature. When the applied pressure was lower than 0.5 MPa, early failure occurred at the joint of the specimens. However, when high pressure was applied, early failure occurred near the joint. To discuss the phenomenon, time-dependent viscoplastic material properties were characterized, and a numerical simulation analysis was performed. Viscoplastic deformation was observed around the bending area, which caused weakness around the bond under high-pressure conditions. A prototype of a Y-shaped heat shield was manufactured and the buy-to-fly ratio was effectively improved using the newly developed process. This study demonstrates the potential of applying the developed process for producing aircraft parts and the importance of viscoplastic behavior for the analysis of final product reliability.

“…The lightweight of automotive parts also reduces engine noise and vibration, and improved durability of components. 1–4 But their high cost limited their use for racing cars and special-purpose cars. Additionally, fabrication cost and the surface finish had to be reduced for high-volume automotive applications.…”

Lightweight and high strength of titanium alloys makes them suitable for automotive industry. Automobiles are in high demand in the future and new materials and technologies are continuously enhancing the performance of automobiles. This research work addresses the potential use and barrier faced by the automobile industry in using titanium alloy. In this experimental study, we tried to overcome the machining challenges faced by industries to machine widely used grade–5 titanium alloy. The machining is performed under a dry machining environment due to ecological and economic concerns. The controllable machining variables and their influence on the tool wear are determined. Statistical analysis is performed to assess the impact of controllable variables. As a result, the optimal parameters setting obtained using the desirability approach, and confirmation runs carried out at optimal conditions. Moreover, a mathematical relation developed using the RSM technique to predict the response. Later on, using better modeling techniques based on artificial intelligence, a better predictive model is developed which forms the basis of cyber physical system.

“…The identified components include intake and exhaust valves, valve springs and retainers, connecting rods, half shafts and axles, mufflers, suspension springs, flywheel housings, and various fasteners. 1,2 However, the high cost of titanium remains an impediment, and it must be lowered if titanium is to be seriously considered as a replacement material. Ford, for example, has estimated that titanium mill products must be priced at $6-$9/lb for some engine applications and no more than $4/lb for most other applications.…”

Overview Light MetalsAlthough titanium has attractive properties that can improve the performance and economy of automobiles, at its current cost, it cannot compete with steel in most applications for which it is suited. It is readily apparent that titanium cannot be considered a viable mass-market automotive materials alternative as long as it is produced with the Kroll process. A look at existing and new technologies (as well as some that have been found lacking) in terms of applicability toward high-volume, low-cost titanium production for automotive applications indicates other options.
