TL;DR: In this article, the Intrinsic Heat Treatment (IHT) was exploited to induce the precipitation of NiAl nanoparticles in an Fe-19Ni-xAl (at%) model maraging steel, a system known for rapid clustering.

TL;DR: A Damascus-like steel consisting of alternating hard and soft layers is created by using a laser additive manufacturing technique and digital control of the processing parameters, showing superior mechanical properties to those of ancient Damascus steel.

TL;DR: FANTASIA and TurPro as discussed by the authors are two major european and german funded projects, focusing on laser additive manufacturing techniques for turbo-engine applications, and they contribute to winning the global leadership of turbo engine manufacturers by developing new flexible and near-net-shape additive manufacturing chains and repair techniques based on Laser Metal Deposition (LMD).

TL;DR: It is found that due to microsegregation, retained austenite exists in the as-LMD- and as-SLM-produced states but not in the conventionally-produced material, and in the peak-aged state, the hardness of SLM- and LMD- produced material is slightly lower than in conventionally -produced material due to the presence of retainedAustenite and reversed Austenite formed during ageing.

TL;DR: In this article, the authors describe and study the thermal profiles experienced by various age-hardenable alloys during laser additive manufacturing (LAM), employing two different manufacturing techniques: selective laser melting and laser metal deposition.
