Abstract
Metals are currently used for medical devices and over 70% of medical implants consist of metals, of which, over 90% are orthopedic implants. Despite the large number of metallic medical devices in use today, they are predominantly made up of only a few metals. Metallic alloys such as titanium continue to be one of the most important components used in orthopaedic implant devices due to favorable properties of high mechanical strength, rigidity, fracture toughness and their reliable mechanical performance as replacement for hard tissues. Beta-Ti alloys containing completely biocompatible elements are exceptionally prospective materials for manufacturing of bioimplants. These biomaterials have the ability to introduce the most important property of biochemical compatibility which is low elastic modulus. However, most of researches on metal are surface modification of titanium materials, while magnesium alloys and titanium alloys are still studied. According to the rise of regenerative medicine, the demand of research on metals is decreasing. On the other hand, many researchers made the effort to substitute metals to polymers or ceramics in medical devices, but still metals occupy a large share. In this presentation, we would like to discuss the evolution, evaluation and development of the modulus of elasticity as an effective factor on the performance of beta alloys and prospective of them in the medical field.
