Abstract Scope |
Processing parameters in laser additive manufacturing are have a profound impact on the structural properties of the deposited MPEA. Optimizing these is crucial and depend on design of experiments (DoE) with a window of three primary variables, viz., laser power, scan speed, and the powder flow rate in a parameter space. We present an approach using Latin hypercube sampling (LHS) as a tool for the DoE of processing parameters in laser additive manufacturing. The DoE using LHS spans a wide range of input parameters that bounds the lower and upper limits of the machine and can be tailored to span a range of energy densities. This technique can be used to systematically investigate the effect of varying processing parameters on the quality of the alloy and narrow the processing window to achieve optimized parameters. We demonstrate this method to fabricate samples of AlCoCrFeNi MPEA to produce dense deposits. |
