Special Issue Information

Dear Colleagues,

Since industrial development began, materials processing is central to the field of materials science and engineering, and is a vital step in manufacturing. Materials processing is an important process for realizing the structural features (e.g., crystal structure, microstructure, size, and shape) required for the product to perform well in the intended application by properly utilizing and designing the composition of a given material. It involves a complex series of chemical, thermal, and physical processes that prepare a starting material, create a shape, retain that shape, and refine the structure and shape. The conversion of the starting material to the final product occurs in three steps: preparation of the starting material, processing operation, and post-processing operation(s). Recently, trends in the high-tech industry are pushing toward miniaturization, the creation of products with complex shapes, and multi-functional materials. To keep up with ever-increasing demands, materials processing has been continuously advancing in terms of production, efficiency and performance qualification.

The main aim of the Special Issue is to discuss the topics of processing, manufacturing, structure/property relationship and applications in advanced materials. All of the single phase and alloy, and composite materials in metals, ceramics, and polymers are of interest.

It is our pleasure to invite you to submit a manuscript for this Special Issue.

The increasing demand for ultra-low carbon steel (Interstitial free steel of Ti-Nb composite stabilized type) has underscored the importance of the RH degassing process, which is critical to achieving stringent quality standards and high productivity. This study aimed to boost decarburization efficiency by expanding the lower volume of the RH degasser and adjusting the circulation gas flow rates (190 Nm3/h, 230 Nm3/h, 250 Nm3/h). The effects of these variations on decarburization time, carbon content, and mechanical properties were systematically evaluated. The Enlarged RH degasser (ERH) achieved a higher decarburization rate than the conventional RH degasser (CRH) at the same gas flow rate of 190 Nm3/h, identifying 230 Nm3/h as the optimal rate for ERH. The experimental decarburization times to reach a carbon content of 0.003 wt% in ultra-low carbon steel were 12.4 min for CRH and 10.8 min for ERH, thus reducing the time by 1.6 min. Conversely, the calculated decarburization times were 13.11 min for CRH and 10.75 min for ERH, with ERH showing a reduction of 2.36 min. Consequently, calculated times were 0.76 min longer than experimental times. No significant differences in inclusions were observed between the CRH and ERH at circulation times of 3, 4, and 5 min; however, the mechanical properties of the ERH showed improvements at 4 and 5 min. Therefore, from an economic perspective, 4 min was established as the optimum time. Ultimately, enhancing the lower volume of the RH degasser has increased productivity and decreased production costs. Full article

Additive manufacturing methods can constitute a valuable alternative to conventional production techniques for components used in the heavy industry, particularly in foundry applications. This innovative manufacturing approach enables an expanded product portfolio as well as higher precision and geometrical complexity of ceramic components. One additive technology applicable to ceramic processing is robocasting, classified within the direct ink writing (DIW) family. In this method, a semi-fluid ceramic paste is extruded to build the part layer by layer; the shaped green body is subsequently fired (sintered) to attain its final functional properties. This study presents the results of materials characterization of printed ceramic filters, encompassing phase composition analysis, density measurements, three-point bending strength testing, hardness, and microstructural examination. The investigations demonstrated that the oxide ceramic Al2O3 processed by the modern robocasting method exhibits mechanical performance at a comparably high level relative to classical manufacturing routes (slip casting, ceramic injection molding, dry pressing). Moreover, the porosity results indicate that 3D printing technology enables lower post-sintering porosity. Full article
