High Performance Machining of Ti-834: Mechanisms of Mierostructural Damage
New civil and military aircraft platforms require an increased amount of aerostructural titanium within their structure. For the advanced manufacturing sector,this surge requires a matched increase in productivity which equates to higher machining surface speeds and machining rates. High resolution electron backscatter techniques were used to identify mierostructural subsurface damage in the form of intense slip bands and mechanical twins, induced during a series of high-speed milling and turning trials carried out on near alpha alloy Ti-834. Such mierostructural features remain undetected by conventional surface integrity techniques and could pose a significant risk to the in service performance as subsurface damage can lead to a significant reduction fatigue crack initiation resistance.
