The Elastic modulus of Pure Titanium and titanium alloy is around 100 GPa, only half of steel, and with high drop strength (shown as the following picture), it can be used in springs, golf head etc. - See: Characteristics of Metals and Implants: - Discussion: - titanium is often selected as a materalial for metal plates or femoral stem implants due to its lower modulus of elasticity (as compared to other alloys); - elastic modulus of stainless steel is 12 times EM of cortical whereas EM of titanium is 6 times of cortical bone; Titanium is extremely durable, corrosion/erosion resistant, and has high intrinsic shock resistance. V.

Some examples of values of the modulus of elasticity (Young's modulus) of materials are as follows: Rubber has a low Young's modulus of 0.01 to 0.1 GPa as it is highly elastic. Zhao, "Self-adjustment of Young's modulus in biomedical titanium alloy during orthopaedic operation", Mater Lett 2, 2011. Young's modulus of elasticity of commercially pure titanium - Grade 2 is about 105 GPa. Modulus of elasticity is also a measure of material's stiffness or resistance to elastic deformation. The Elastic modulus of Pure Titanium and titanium alloy is around 100 GPa, only half of steel, and with high drop strength (shown as the following picture), it can be used in springs, golf head etc. Compute the maximum length of the specimen before deformation if the maximum allowable However, the elastic properties of the ω phase have remained unclear because of the difficulty in preparing a large single crystal consisting of a single phase of the ω phase . Due to their higher modulus of elasticity than titanium, they permit an adequate micro movement to distribute force to the implant body. The Modulus of elasticity of Grade 2 titanium at room temperature (70°F) is only approximate half of that of the low carbon steels and conventional austenitic stainless steels. Solutions for Chapter 17 Problem 33P: A titanium alloy with a modulus of elasticity of 110 × 103 MPa is used to make a 454 kg part for a manned space vehicle. The elas-tic modulus of -type titanium alloys is noticeably lower than that of -type titanium (CP Ti) and ( + )-type alloys [1,6,18-18]. Meanwhile, there is a . This indicates that the ability of titanium to resist normal strain is lower than that of steel, so the use of titanium is limited and it is not suitable for rigid structural parts. Like other titanium alloys, Ti 64 has a modulus of elasticity of 107 Gpa (16.5 x 103 ksi), roughly half that of carbon steels. High modulus of elasticity—Titanium is very "springy." For a given force, it will deflect more than steel, which results in a higher likelihood of vibration, chatter, and poor chip formation. The elastic modulus of titanium is 106.4GMPa at room temperature, which is 57% of steel. (a) Compute the modulus of elasticity for the nonporous material.

The flexure m … The elastic modulus of titanium decreases with increasing temperature. It relates stress (force per unit area) to strain (proportional deformation) along an axis or line.The basic principle is that a material undergoes elastic deformation when it is compressed or extended, returning to its original shape when the load is removed. 70.
