Abstract Scope |
The choice of processing parameters used for product fabrication in laser-based additive manufacturing is as critical as the property requirements the product is meant to conform to. Part qualification is dependent on establishing a reliable processing strategy to produce parts in a repeatable manner, that conforms to the desired property requirements. This paper discusses the process used to produce titanium alloy samples with improved build integrity and mechanical properties. Samples fabricated at optimized parameters showed an optimized microstructure that reported less defects and improved mechanical properties, such as hardness and tensile properties. The material showed a decrease in stiffness, while the yield and tensile strengths showed improvements. The tensile elongation showed an improvement of 11% due to parameter optimization. |
