Abstract


Titanium is came out on top in many areas. A major advantage of titanium alloys from a medical point of view is avoiding chemicophysical reactions, eliminates the danger of a metal allergy so that it is fully biocompatible. Especially, commercially pure titanium is used in medical applications due to its purity. From material scientist point of view, most significant properties of titanium is higher corrosion resistance and the highest strength-to-density ratio. In this manner, titanium alloys are proven themselves in medical applications and also, finding new titanium alloys are in the interest of many material scientist. This paper reports investigations of the microstructure and mechanical behaviors of com-mercially pure titanium (Grade 4) bars produced by cold drawing. Accordingly, microstructural analysis are performed by using Scanning Elec-tron Microscopy (SEM) techniques. In order to examine the mechanical behaviors of CP-Titanium Grade 4, tensile test, hardness test and Char-py-impact test with a different temperatures are practiced. These results indicated that CP-Titanium has higher tensile strength but lower impact toughness.
