“…Currently, materials produced by selective laser melting (SLM) technologies are regarded as a new class of structural materials, while SLM is considered as an advantageous technology for designing complex-shaped metal products for prospective applications in mechanical engineering, biomedicine, the power industry, etc. [ 1 , 2 , 3 , 4 , 5 ]. Active research is underway into SLM materials and by now the effect of melting modes on the density, structure, and physical and mechanical properties of various SLM materials has been studied comprehensively [ 6 , 7 , 8 , 9 , 10 ].…”

The interaction of hydrogen with specimens of 316L steel and Inconel 718 alloy processed by selective laser melting (SLM) was studied. The effect of hydrogen on the mechanical properties of SLM materials, hydrogen permeability, and microstructure was investigated; besides, these values were compared with the properties of conventionally produced materials. It was shown that SLM can be successfully used to produce parts for operation in hydrogen environments at high pressure at room temperature.

“…The SLM technology used in this paper to fabricate porous specimens is described in the literature [28], and the metal powders were made from AlSi10Mg. The pore structure of the prepared sample is a composite porous structure with two pore forms: micropores on the surface of the solid framework and micropores inside the framework.…”

Surface porosity is an important means of enhancing boiling heat transfer. In this paper, two kinds of composite porous structures of surface micropore + square channel and framework micropore + square channel were prepared by selective laser melting technology using AlSi10Mg as the powder material. The effect of composites with different pore forms on boiling heat transfer was investigated in pool boiling experiments. It was found that controlling the thickness of the powder layer manufactured by selective laser melting can change the surface roughness of the sample, and the sandblasting treatment reduced the surface roughness of the samples. The average heat transfer coefficient of the rough surface composite porous structure sample was increased by 40% compared to the sandblasted sample. The micropores on the surface of the sample and inside the framework significantly enhanced the heat transfer coefficient of the composite porous structure. The presence of surface micropores increased the heat transfer area and the vaporization core density of the composite porous structure and exhibited excellent heat transfer coefficient improvement in the low heat flux region. The framework microporous composite porous structure can form effective gas–liquid diversion at high heat flux and obtain higher heat transfer performance. The large channel in the composite porous structure is the key control factor of the critical heat flux.
