Metal additive manufacturing in the commercial aviation industry: A review (2019, background): “Components often have purposely induced residual stresses: for example, rapid cooling can induce compressive residual stress on the part surface and tensile stress in its interior, hence improving its mechanical strength [123-125].”
Effect of Process Parameters on the Generated Surface Roughness of Down-Facing Surfaces in Selective Laser Melting (2019, methodology): “conducted a process optimization with the primary goal of maximizing part density, they identified the cooling rate to be important for the microstructural evolution and proposed methods to maintain a high energy input, which results in high cooling rates, thereby tailoring the microstructure and re”
Recent innovations in laser additive manufacturing of titanium alloys (2024, background): “The effects of these process variables on the fabricated part’s relative density have been well-reviewed and discussed previously [13–15 , 27– 29 ].”
