A Review on the Properties of β Type Ti Alloys: Microstructure, Mechanical, Corrosion Properties and Production Methods

The biomedical material industry continues to grow worldwide for people to sustain their quality of life and related activities. The increase in the aging population and prosperity level are among the main reasons that the biomedical material industry growing rapidly. According to the characteristic properties of the region where implantation will be performed within the body, the preferred material group varies. Among these materials, metallic biomaterials have a high usage rate due to their superior mechanical properties. As with the issues faced in polymer-based, ceramic-based, and composite materials the problems triggered by metallic biomaterials in patients take place by cause of many reasons. Innovative solutions are produced today with the developing technology and the effort done against to the problems. Whereas metallic biomaterials cause biomechanical unsuitability with their high modulus of elasticity, they threaten biocompatibility by producing a poisonous effect because of toxic alloy element ions. Therefore, the characteristics of beta-type Ti alloys were explored which were created to address two basic issues: they were alloyed with elements with excellent biocompatibility and had a low modulus of elasticity owing to their phase structure. Furthermore, the effects of the production methods on beta-type Ti alloys were highlighted and the effectiveness of alloys created with powder metallurgy technology was analyzed at this step.
