dc.description.abstractDue to the large energy input during the laser powder bed fusion process, some elements of metal alloy will reach vaporisation temperature. Significant differences between the volatility of various elements in the alloy may change the chemical composition after manufacturing. This study used this preferential evaporation effect to control the final composition to a targeted value, potentially for alloy and component tracing. Different laser process parameter sets were studied, and the mechanical properties changes associated with various compositions were investigated.
