The exact composition and thermal history controls the phase distribution and morphology of the alloy and hence determines the resulting properties. The use of titanium alloys increased significantly in the 1980s, particularly in the construction of combat aircraft as opposed to transport aircraft. Titanium forms hydrides with hydrogen and alloys are susceptible to hydride-induced cracking in a manner similar to zirconium alloys (Hua et al., 2005; Shoesmith, 2006). wrought counterparts over the more commonly used Ti-6Al-4V. It has excellent strength, compared to commercially pure titanium, but yet retains the stiffness and thermal properties that are so important. A passive oxide film (primarily of TiO2) protects both Ti-6Al-4V and CPTi alloys. Grade 9 titanium, for example, contains strength somewhere in between commercially pure grade 4 titanium and grade 5 titanium, while being able to operate at higher temperatures than the commercially pure grades. allotropic behavior of titanium allows diverse changes in microstructures [117] compared the mechanical strength of titanium alloy and SS volar distal radius locking plate in fixation of AO-C3 fracture type. products and over 1725 MPa for special forms such as wires and springs. In bones with low mineral density, bone grafting has been utilized to enhance the bone healing in conjunction with titanium implants. The mean corrosion rate of Ti Grade 7 in aerated aqueous solutions is 20 nm/year, with the rate reported to be independent of temperature (within the range 60–90°C) and salinity (up to several mol/L) (Hua et al., 2005). castings in the United States increased by 260% between 1979 and 1989. All Ti-6Al-4 V castings are hot isostatic pressed to ensure structural integrity. The products made from pure titanium in these applications require high processability that alloys cannot provide.
such as static and rotating gas turbine engine components. Nitriding can increase surface hardness and form two types of surface layers; a nitrogen compound layer and a nitrogen diffusion layer. Comparison Between Titanium and SS Plates, E. Kaivosoja, ... M. Takagi, in Wear of Orthopaedic Implants and Artificial Joints, 2013. Ti-6Al-4 V implants are generally classified by one of the three forming methods (cast, wrought or forged). These titanium net shape technologies include powder metallurgy (P/M), temperatures. These desirable properties make Ti-6AL-4V a popular choice in several industries including medical, marine, aerospace and chemical processing. Titanium alloys are known to have two primary phases. Grade 9 is comprised of titanium, 3% aluminum, and 2.5% vanadium.
Cast alloys have a metallurgically stable homogeneous structure. The higher stiffness of SS contributed to higher nonunion rates. by variations in thermomechanical processing, a broad range of properties
