Special Issue Information

Dear Colleagues,

Powder metallurgy allows for versatile materials design with respect to conventional casting metallurgy, and has been used to fabricate advanced materials including oxide-dispersion-strengthened metallic materials, refractory metals and associated alloys, metal matrix composites/nanocomposites, nanostructured/ultrafine-grained/heterostructured metallic materials, etc. These high-performance powder metallurgy materials are currently being extensively used as structural components/parts or showing great potential in structural applications. With the coming of the emerging additive manufacturing technology, the design and fabrication of very complex-shaped powder metallurgy materials become possible. This significantly advances the development of novel powder metallurgy materials with extremely complex shapes.  In addition, to improve the direct sustainability of structural metals, solid-state recycling of metal chips/scraps via powder metallurgy route is receiving increasing attention.

This special issue will mainly cover metallic materials, including metals, alloys, and metal matrix composites, fabricated by either powder metallurgy route or additive manufacturing technology. The topics on solid-state recycling of metals, rapid sintering of metallic powders and other relevant studies are also warmly welcome to contribute to this issue. We cordially invite you to submit full papers, communications and reviews to present and discuss your recent findings on the following areas:

  • Powder metallurgy Al alloys
  • Powder metallurgy titanium and titanium alloys
  • Nanostructured and ultrafine-grained metals and alloys fabricated by powder metallurgy
  • Metal matrix nanocomposites fabricated by powder metallurgy
  • Heterostructured metals, alloys and composites fabricated by powder metallurgy
  • Spark plasma sintering
  • Additively manufactured metals and alloys
  • Solid-state recycled materials

This paper reviews the production of sinters using the spark plasma sintering method. SPS (spark plasma sintering) technology has been used for several decades, mainly in laboratories, to consolidate a huge number of both new and traditional materials. However, it is now more often introduced into practical industrial use, with equipment as early as the fifth generation capable of producing larger-size components at competitive costs. Although the mechanism of sintering with the use of this method is not yet understood, the effectiveness of the SPS process for the rapid and efficient consolidation of a wide range of materials with novel micro-structures remains indisputable. With a relatively wide variation in chemical composition, the structure allows the selection of appropriate consolidation parameters for these materials. The influence on the values of apparent density and mechanical properties depends on the parameters of the spark plasma sintering process. In order to achieve a density close to the theoretical density of sinters, optimization of the sintering parameters, i.e., sintering temperature, heating rate, sintering time, pressing pressure and protective atmosphere, should be carried out. In this paper, the optimization of spark plasma sintering of Si3N4–Al2O3–ZrO2 composite was carried out using the Taguchi method. The effects of four sintering factors, namely heating rate, sintering time, sintering temperature and sintering pressure, on the final density were investigated. Optimal sintering conditions were proposed and a confirmation experiment was conducted. The optimal combination of sintering conditions for spark plasma sintering (SPS) of Si3N4–Al2O3–ZrO2 composite for high apparent density was determined as A3-B3-C3-D2. Based on ANOVA analysis, it was found that the apparent density of sintering was significantly influenced by sintering temperature, followed by pressing pressure, sintering time and heating rate. Validation of the developed mathematical model predicting the apparent density of sinters showed close agreement between the predicted response results and experimental results. Full article
