Special Issue "Perspectives on Additively Manufactured Metallic Materials"
A special issue of Materials (ISSN 1996-1944).
Deadline for manuscript submissions: 15 May 2018
Recent advances in additive manufacturing (AM) techniques offer many opportunities in terms of design freedom. Complex geometries that could not be easily manufactured using conventional techniques are relatively easy to manufacture using AM. AM of metals has been receiving particular attention, because functional parts in the various industrial sectors can now be fabricated using AM techniques. This Special Issue is, therefore, dedicated to the various areas of research relevant to metal AM. The processing parameters are known to be particularly important in metal AM. The relationship between processing parameters and the resulting microstructure and mechanical properties is one of the most important aspects that need to be studied. Process monitoring and (real-time) adaptation of processing parameters are also of great importance to enable first-time-right AM of metals. Furthermore, the quasi-static and fatigue behavior of AM metallic materials are not yet well understood and will be also covered in this Special Issue. Designer materials, where the microstructure and, thus, mechanical properties of AM materials are (locally) ‘designed’ and achieved through adjustment of processing parameters are also of interest. Finally, AM of new materials, development and improvement of new AM processes and systems, standardization of AM processes and materials, quality control in metal AM, metal powder characterization and standardization, and the other relevant aspects of metal AM are also of interest.

Abstract: Considering the environment factors, there are no absolute same pieces in selective laser melting(SLM), so it is difficult to reproduce defaults in product. Because the physical phenomena occur over a broad range of length and time scales and there are so many process parameters in SLM, the time cost and material cost are high to find rules that defaults occur by doing experiments and simulations. Most mechanical properties have strong relationships with microstructure. Microstructure is one important factor that affects the mechanical features of metal part and different transformation of thermal field will result different microstructure. Therefore, in this paper some research work has been done to find the mechanism of microstructure generation in SLM. Some experiments are designed and done to find the effects of thermal field transformation on microstructure in SLM. Firstly, different scanning paths are taken and the thermal field of every layer is recorded; secondly, the microstructures of the parts are got with scanning electron microscope(SEM); thirdly, data mining and statistical analysis technology is used to analyze the effect of thermal field transformation on microstructure.
