“…The microstructure of the 316L sample fabricated by selective laser melting is shown in Figure 5. It displays a fine cellular/dendritic structure, similar to most of the samples prepared by SLM during to the fast cooling rates observed during the process [14][15][16][17][18][19]. This also explains the microstructural differences between the SLM prepared and conventionally cast/powder metallurgical microstructures.…”

Abstract:The compression behavior of different 316L steel cellular dodecahedron structures with different density values were studied. The 316L steel structures produced using the selective laser melting process has four different geometries: single unit cells with and without the addition of base plates beneath and on top, and sandwich structures with multiple unit cells with different unit cell sizes. The relation between the relative compressive strength and the relative density was compared using different Gibson-Ashby models and with other published reports. The different aspects of the deformation and the mechanical properties were evaluated and the deformation at distinct loading levels was recorded. Finite element method (FEM) simulations were carried out with the defined structures and the mechanical testing results were compared. The calculated theory, simulation estimation, and the observed experimental results are in good agreement.

“…Contrary to SLS, SLM is claimed to be difficult to control the process [18] and hence the quality of the product. On the other hand, when compared with the conventional metal casting process, SLM not only enables fabrication of complex geometries but also enhances design flexibility and provides a fine microstructure components due to the higher cooling rate [19]. As a result, better mechanical strength is expected.…”

Abstract-In the recent years, the additive (layer) manufacturing technology, which emerged about three decades back, to assist design conceptualization and visualization through rapid prototyping, has created application interests beyond rapid prototyping. This transition beyond prototyping, i.e. transition to production of functional parts is driven by several other progresses including availability of advanced printing machines and materials including metal printing capabilities. Among others, the unlimited geometrical complexity, low material wastage, environmental friendly and in most cases economically viable operations of additive manufacturing are the key factors that attract diverse industrial sectors to further explore the potentials of this technology for production of fully functional parts. There even exists a sense of feeling, at many corners, that this technology will significantly change the global economy and the way business is done in the future, in a similar way the www technology and the smart phone technology did. Aimed to put a very small drop into this potentially huge future research and development area and based on existing experiences, published works and ongoing research activities, this article shades light on the prospects of the additive manufacturing technology as a production method for the future industry. Two of the most potential technologies, fused deposition modeling and selective laser melting, are described and potential challenges highlighted. In line with the national interests and international focus, the medical sector and the offshore oil and gas industry are identified as the best beneficiaries if additive manufacturing is used for functional part production.

“…The required magnetic properties are usually large saturation magnetization, low coercive field and high magnetic permeability. Fe-based metallic glasses can be characterized by their chemical compositions containing metalloids (B, Si, P), other metals (Co, Ni, Cu, Zr, Hf, Mo, Nb, Al, Ta) and also rare earth elements [1][2][3][4][5][6].…”

Magnetic Properties and Structure after Crystallization of Fe_80-xB₂₀Nb_x (x=4, 6, 10) Metallic Glasses

The ferromagnetic Fe-based amorphous alloys were studied due to properties for soft magnetic applications. Depending on different Nb addition, the formation of crystalline phases after annealing of amorphous Fe80−xB20Nbx (x = 4, 6, 10) alloys was studied. The crystallization products as well as the phase structure were determined using the Mössbauer spectrometry combined with differential scanning calorimetry and magnetic measurements. The addition of Nb caused a shift of crystallization process towards higher temperatures and induced changes in coercive force and decreased the saturation magnetization. It was found that Nb addition changed the crystallization process from single crystallization for Fe76B20Nb4 alloy to binary crystallization in the Fe74B20Nb6 and Fe70B20Nb10 glasses. The annealing process at the onset crystallization temperature induced complex phase formation including the α-Fe, Fe3B, and Fe2B phases for alloys x = 4, 6.
