A Critical Review on Effects of Residual Stresses on Machining of Titanium alloys by various Non-Conventional Processes

Abstract

Titanium alloys possess some excellent properties that make the material of choice in many important industries. However, as titanium alloys undergo various kinds of machining operations in these industries, residual stresses may be generated within them, that can lead to significant reduction in their fatigue performance. Since titanium alloys are best machined by non-conventional processes, it is necessary for industry professionals working with titanium alloys to have accurate knowledge about residual stresses for optimum designing and manufacturing of reliable and safe components. This paper presents a critical review on the studies done by various authors to investigate the effects of residual stresses generated within titanium alloys under different non-conventional machining processes, so as to compile the available literature for the reference of industry professionals who work with titanium alloys. Keywords: Residual stresses, non-conventional machining, Titanium alloys, fatigue strength, residual stress measurement
