Abstract Scope |
In this work, selective laser melting with varying laser power, laser speed, hatch spacing and layer thickness is used to manufacture more than 200 samples of 316 L stainless steel. Properties that can be rapidly measured such as density and hardness are used as initial parameters to rapidly down-select 9 samples out of the initial 200 samples. These 9 samples are then characterized and their mechanical response under uniaxial stress and strain conditions measured. Specifically, spall recovery experiments are performed on these 9 samples to determine if any relationships exist between the dynamic strength of the material and the processing parameters. Our work shows that there exists a critical laser power and hatch spacing that does indeed lead to optimum spall strength. The results from these dynamic experiments that open avenues for material design using AM will be discussed in this talk. |
