Abstract

Titanium present in the earth’s crust at a level about 0.6% and is therefore the fourth most abundant structural metal after aluminum, iron, and magnesium. High strength, low density, and excellent corrosion resistance are the main properties that make titanium attractive for a variety of applications. The major application of the material is production of airframes, engine components ,steam turbine blades, superconductors, missiles etc. The titanium has good corrosion resistance which makes it excellent use in marine services, chemical, petrochemical, electronics, biomedical industries. Titanium and its alloys are among the most difficult materials to machine, mainly because of the metal reactivity at medium to high temperatures, from which a tendency to weld to the tool while machining leads to chipping and premature tool failure. Additionally, its low heat conductivity increases the temperature at the tool-workpiece interface. Finally, the low elastic modulus of Ti allows relatively large deflections of the workpiece, which affect adversely the tool life. In this paper we study the machinability aspects of titanium grade 2 ( commercially pure titanium ). It has outstanding corrosion resistance and useful strength (similar to austenitic stainless steels) at low density. It has good weldability and is easily formable. It is the most commonly used grade of titanium.
