An overview of powder granulometry on feedstock and part performance in the selective laser melting process (2017, background): “Under this thermo-capillary action, the molten metal further traverses through the bed of powder particles to join the pre-consolidated underlying layer and solidifies rapidly under cooling rates of about 10(6)K/s [32].”
Thermal behavior of the molten pool, microstructural evolution, and tribological performance during selective laser melting of TiC/316L stainless steel nanocomposites: Experimental and simulation methods (2018, background): “This transition to tribolayer formation is expected to reduce the wear rate in the sliding tests, as was suggested by Tjong (2007) to explain the uniform distribution of nanoscale TiC reinforcements with lower interfacial stresses in the matrix, and thus minimal nanocomposite breakage during sliding”
Denudation of metal powder layers in laser powder bed fusion processes (2016, background): “On the one hand, grain refinement hardening or internal dislocation effects through the rapid thermal cycling typical of LPBF can lead to stronger materials compared with more traditional methods [3].”
