Optimisation of selective laser melting parameters for the Ni-based superalloy IN-738 LC using Doehlert’s design

Purpose The Ni-based superalloy IN-738 LC is known to be susceptible to porosity and different types of cracking during the build-up process and, thus, challenging to manufacture using selective laser melting (SLM). Determining a feasible set of operating parameters for SLM of nickel-based superallo... View More
