Enhancing the Machinability of Titanium Alloy (TI6AL4V): A Comprehensive Review of Literature

Abstract

<div>Titanium alloys (Ti-6Al-4V) are alloys, which contain a mixture of titanium</div><div>and other elements. The alloy boasts excellent mechanical properties such as high</div><div>toughness, high strength to weight ratio, and good corrosion resistance ability. Its</div><div>excellent mechanical properties as well as its suitability for high temperature</div><div>applications, make it fit for many industrial applications. However, titanium alloy has</div><div>low thermal conductivity, which makes it susceptible to poor machinability and</div><div>dimensional inaccuracies during machining operations. In this study, a comprehensive</div><div>review of the literature was carried out in order to identify the various strategies</div><div>suitable for enhancing the machinability of titanium alloy (Ti-6Al-4V). The findings</div><div>from the survey indicate that the machinability of titanium to the required surface finish</div><div>can be enhanced in the following ways: use of effective cooling strategies, process</div><div>design, optimisation of process parameters, selection of appropriate cutting tool,</div><div>effective process monitoring and control as well as the selection of the optimum range</div><div>of process parameters, etc. It is envisaged that the findings of this work will assist</div><div>machinists in their quest to achieve sustainability during the cutting operations of</div><div>titanium alloy.</div>
