Anisotropic tensile behavior of Ti-6Al-4V components fabricated with directed energy deposition additive manufacturing (2015, background): “In terms of differential thermal histories, the lower portion of the wall, which is closer to the baseplate, cools more rapidly than the upper portion [40], in which the heat must escape either by convection outward or conduction down the height of the wall [35].”
Laser cladding as repair technology for Ti–6Al–4V alloy: Influence of building strategy on microstructure and hardness (2015, methodology): “This fast cooling effect can diminish if the substrates (or pre-existing layers) warm up during building of successive layers [7].”
Massive nanoprecipitation in an Fe-19Ni-xAl maraging steel triggered by the intrinsic heat treatment during laser metal deposition (2017, unknown): “This type of Intrinsic Heat Treatment (IHT) consists of sharp temperature pulses up to temperatures close to the melting point [5,8,9].”
Towards understanding grain nucleation under Additive Manufacturing solidification conditions (2020, background): “A review of the literature suggests that depending upon the process, the thermal gradient can range from 10 5 to 10 7 Km -1 and the cooling rates can vary between 10 2 and 10 6 Ks -1 [4-19].”
Anisotropy and heterogeneity of microstructure and mechanical properties in metal additive manufacturing: A critical review (2018, background): “A common microstructure feature observed in metal AM parts was the epitaxial columnar grain morphology [11, 15, 38, 43, 84-86].”
Precipitation and austenite reversion behavior of a maraging steel produced by selective laser melting (2014, background): “, the material in one layer is in the heat-affected zone of the layer above (and even subsequent layers, with diminishing intensity).(4,5,7) This might lead to clustering or to nucleation of precipitate phases during this “intrinsic heat treatment.”
