Summary: Addressing the strength-ductility dilemma in Inconel 718 superalloy using traditional strengthening strategies is challenging. This study proposes a novel strategy of combining laser powder bed fusion (LPBF) with thermomechanical treatment to simultaneously improve the strength and ductility of Inconel 718. The study demonstrates the outstanding strength-ductility synergy achieved through finer grains, annealing twins, coherent nano-precipitates, and additional microstructures induced by tensile loading.

Summary: This study investigates the effect of Al addition on the microstructure and microhardness of Inconel 718 superalloy fabricated by laser additive manufacturing. The addition of Al promotes the precipitation of different phases and increases hardness, but also intensifies the segregation of Nb element, leading to the formation of Laves phase.

Summary: The study showed that the high-cycle fatigue properties of Inconel 718 (IN718) superalloy prepared using laser directed energy deposition (LDED) and subjected to a specified heat treatment scheme exhibit significant differences at room temperature and high temperatures. The fatigue limit is higher at room temperature and lower at higher temperatures, with fatigue limits only about 77% and 63% of the values observed in wrought alloys, respectively. Furthermore, the fatigue failure mode of HSA IN718 alloy changes with increasing test temperature.

Summary: The effect of pulse duration on molten pool morphology and solidification texture in single-track and bulk Inconel 718 samples fabricated using pulsed laser additive manufacturing was investigated. Short pulse durations result in uniform grains, while long pulse durations lead to alternately distributed coarse grains in the overlapping region and fine grains at the center of the molten pool.

Summary: This study investigates the microstructure and mechanical properties of Ti6Al4V parts produced by selective laser melting in the early stage of solid-state diffusion bonding. Higher diffusion temperature reduces voids on the bonding interface and improves mechanical properties of the joint. The joints consist of criss-cross acicular alpha ' martensitic structure, with the volume fraction of martensitic alpha ' decreasing with bonding temperature increase.
