Abstract

This work is a compilation and summary of the quasi-static mechanical properties of a novel cobalt-free maraging steel, M789, that underwent a series of various heat treatments which included solution annealing, intercritical annealing, and aging temperatures. This work utilized a single laser powder bed fusion (PBF-L) build to ensure uniform chemistry of the batch of specimens. The tensile geometry consisted of miniaturized tensile specimens, and were tested to failure to asses properties such as the yield strength, ultimate tensile strength, uniform elongation, elastic modulus, and total elongation. The results are presented in tabular and graphical format.
