Abstract

OOSTHUIZEN, G.A.; AKDOGAN, G.; DIMITROV, D.  and  TREURNICHT, N.F.. A Review of the Machinability of Titanium Alloys. R&D j. (Matieland, Online) [online]. 2010, vol.26, pp.43-52. ISSN 2309-8988.

Titanium alloys find wide application in many industries, due to their unrivalled and unique combination of high strength-to-weight ratio and high resistance to corrosion. The machinability of titanium alloys is impaired by their high temperature chemical reactivity, low thermal conductivity and low modulus of elasticity. In this paper, the machining fundamentals specific to titanium alloys are presented and the machining of Ti6A14V with conventional and advanced cutting tool materials is reviewed. The experimental results from several sources are discussed and form the basis of a collaborative research project between academia and industry. The selected aerospace benchmark component is presented and milling strategies for machining performance enhancement are discussed.

Keywords : Ti6A14V; manufacturing.
