Tailoring the microstructure and mechanical properties for Hastelloy X alloy by laser powder bed fusion via scanning strategy

Irregular large pores induced by laser powder bed fusion (LPBF) are inherent defects, which greatly domain the mechanical properties of as-built components. Laser remelting is an effective method to diminish the porosity and increase the energy input, while excessive heat accumulation is generally a...
