TL;DR: In this paper, powder metallurgy (P/M) titanium matrix composite (TMC) reinforced with the CNTs was prepared by spark plasma sintering (SPS) and subsequently hot extrusion process.
TL;DR: In this article, the authors used scan electron microscopy and X-ray diffraction techniques to study the fracture mechanism and phase identification of a composite specimen, which is characterized by ridges, voids, cracks, dimples, particle fracture and ridges.
TL;DR: The MoS2/titanium composite (high titanium) self-lubricant (MoST™) was developed by Fox et al. as mentioned in this paper and has a coating hardness of 500 HV, a coefficient of friction of 0.02 during 100 N applied load reciprocating wear testing, and a low wear rate.
Abstract: As previously reported (Fox et al., Proc. PSE Conf., Garmisch Partenkirchen, 14–18 September, 1998), the properties of MoS2 coatings can be improved by the co-deposition of a small amount of titanium. These MoS2/Ti coatings, known as MoST™ produced by closed field unbalanced magnetron sputtering, are harder, much more wear resistant and less sensitive to atmospheric water vapour. These coatings have given excellent industrial results for a wide range of cutting and forming applications. Two forms of these MoS2/titanium composite coatings have been developed: MoS2/titanium composite (low titanium, 10 at%) and MoS2/titanium composite (high titanium, 20 at%).
The MoS2/titanium composite (low titanium) exhibits a coating hardness of 500 HV, a coefficient of friction of 0.02 during 100 N applied load reciprocating wear testing, and a low wear rate, while the MoS2/titanium composite (high titanium) exhibits a coating hardness similar to that of TiN, a coefficient of friction of 0.04 during 100 N applied load reciprocating wear testing, and an extremely low wear rate.
The choice of coatings is dependent upon the application. Recent industrial performance data related to the characteristics of these MoS2/titanium composite (high titanium) self-lubricant coatings, which are utilised now in large-scale production, are presented.
TL;DR: A titanium alloy which contains 30 to 60 wt. % of an element of Va Group (Vanadium Group) and the balance consisting substantially of titanium, has an average Yang's modulus of 75 GPa or less and a tensile strength at elastic limit of 700 MPa or more as mentioned in this paper.

The titanium alloy can be used for various products requiring a low Yang's modulus, a large elastic deformation and also a high strength.
TL;DR: A consumable billet for melting and casting a metal matrix composite component is made of a consolidated powder metal matrix composites having a titanium or titanium alloy matrix reinforced with particles as discussed by the authors.
Abstract: A consumable billet for melting and casting a metal matrix composite component is made of a consolidated powder metal matrix composite having a titanium or titanium alloy matrix reinforced with particles. The preferred billet is a blended and sintered powder metal composite billet incorporating titanium carbide or titanium boride into a Ti--6Al--4V alloy.
