Net Shape Processing of Titanium Alloys for Enhanced Performance and Improved Affordability
Net shape processing methods offer both cost and performance advantages over the fabrication of titanium alloy components from conventional ingot metallurgy. While many net shape processing methods are well established in niche markets, the emergence of additive manufacturing in the titanium aerospace market offers the potential for revolutionary advances in cost reduction and performance enhancement. From an affordability perspective.net shape processing can limit the need for cost intensive thermomechanical post processing operations. This is especially important for titanium alloys that are relatively difficult to handle at elevated temperatures,and challenging to mechanically work into useful shapes. Net shape processing also limits or eliminates the need for costly machining operations, which can account for a significant fraction of the overall production cost,especially in the aerospace market. Beyond affordability,net shape manufacturing can also provide a means for creating novel alloy compositions and microstructures through non-equilibrium solidification,solid-state consolidation,and gradient compositions. This paper reviews the broad capabilities for net shape processing of titanium alloy structures and offers a detailed assessment of additive manufacturing techniques for the low cost fabrication of advanced titanium components.
