Special Issue Information

Dear Colleagues,

We are delighted to announce the launch of a Special Issue on "Symmetry/Asymmetry in Manufacturing and Machining of Advanced Materials". The manufacturing and machining of advanced materials are crucial to rapid development in the industrial field and play a vital role in aerospace, aviation, navigation, transportation, and other industries. Advanced manufacturing and machining technologies are the foundation for the high-performance materials used in these industrial fields and are essential for the rapid development and upgrading of these materials. The purpose of this Special Issue is to uncover the profound impact of symmetry/asymmetry in the manufacturing and machining of advanced materials, revealing emerging trends and cutting-edge research. We invite researchers from these fields to submit their innovative work in the following areas:

  • Continuous casting;
  • High-pressure casting;
  • Squeeze casting;
  • Direct-chill casting;
  • Centrifugal casting;
  • Counter-pressure casting;
  • Spray forming;
  • Additive manufacturing;
  • Semi-solid forming;
  • Powder sintering;
  • Heat treatment;
  • Extrusion;
  • Forging;
  • Rolling;
  • Equal channel angular pressing;
  • Drawing;
  • Bending;
  • Electromagnetic forming;
  • Hydroforming;
  • High-pressure torsion;
  • Welding;
  • Surface treatment;
  • Electrochemistry;
  • Corrosion;
  • Cast-rolling;
  • Stamping.

We encourage researchers to submit their original research articles, reviews, or perspectives that explore the role of symmetry and asymmetry in the manufacturing and machining of advanced materials. This Special Issue provides researchers with an opportunity to share novel insights, methodologies, and applications, shaping the future of the field.

The process of symmetrical multidirectional pressure was adopted to inhibit the macrosegregation of eutectic Si in squeeze cast A356 alloy. Five pressure modes were applied to study the effects of multidirectional pressure and the timing of pressure application on the macrosegregation of eutectic Si. The results show that the directional movement of the solute-rich liquid phase could be inhibited by symmetrical multidirectional pressure. Therefore, the macrosegregation of eutectic Si in the casting part was inhibited. Moreover, the timing of pressure application should be matched with the local pressure position. After the effective inhibition of the macrosegregation of eutectic Si, the elongation of the alloy was significantly improved, reaching up to 7.12%. In addition, the plastic deformation region was observed at the local pressure position. The grains in the plastic deformation region were refined. The proportion of low-angle grain boundaries in the deformed region was about 30%, which was much higher than that in the other undeformed region. The size of the Fe-containing intermetallics in the deformed region decreased to 5–10 μm, which is favorable for the mechanical properties of the alloy. Full article
