Special Issue Information

Dear Colleagues,

The processing–structure–properties relationships are the basic guiding principles in design, development and application of materials, and represent the core of materials science and engineering. The close relationship among the processing parameters, microstructure, and mechanical properties is a matter of interest in different areas such as foundry, plastic forming, sintering, welding, etc., and is relevant for both well-established and innovative processes. 

With the development of various advanced manufacturing methods, the manufacturing of advanced materials has been significantly improved. However, the relationship of process–structure–properties requires in-depth investigation. Processing parameters are usually provided by the machine manufacturer as a range of error. The challenge in relating parameter errors to processing is that the parameters are also related to microstructural characteristics, which can subsequently govern the mechanical performance of the corresponding materials. The development of predictive modeling, based on the understanding of the relationships between process parameters, microstructure evolution, and mechanical properties, is a potentially key ingredient in this optimization process. The development of predictive methods based on a fundamental understanding of process–structure–properties relationships could make a significant contribution to the increased uptake for industrial production.

Based on the above, it is my pleasure to invite you to submit a manuscript for this Special Issue. This Special Issue aims to report recent advances in processing–structure–properties relationships for structural materials and various ways to push their limits towards industrial applications. Full papers, communications, and reviews are all welcome. Potential papers include—but are not limited to—the following subjects:

  • Superalloys;
  • Steels;
  • Coatings;
  • High-temperature ceramics;
  • Additive manufacturing;
  • Materials design, processing and property

In this work, were synthesized (Pb0.91La0.09)(Zr0.65Ti0.35)0.9775O3 ceramic materials with different concentrations of praseodymium (0, 0.1, 0.3, 0.5, 1 wt.%) via gel-combustion route and sintered by the hot uniaxial pressing method. Measurements were conducted on the obtained ceramics using X-ray powder diffraction (XRD), scanning electron microscope (SEM), EDS analysis, and examination of dielectric and ferroelectric optical properties. Results give us a detailed account of the influences of the praseodymium ions on the structural, microstructural, and dielectric properties. 3D fluorescence maps and excitation and emission spectra measurements show how a small admixture changes the ferroelectric relaxor behavior to an optically active ferroelectric luminophore.

To investigate the micro-grinding process and performance of 2.5D Cf/SiC composites and 2.5D SiCf/SiC composites in depth, single-factor micro-grinding experiments were conducted by using SiC ceramics as a comparison. Differences in the material removal process, surface microstructure, surface roughness, and grinding force of the three materials under the same grinding parameters were comparatively analyzed. The results indicate that crack propagation is severe during the micro-grinding process of SiC ceramics. The ground surface is uneven, accompanied by pit defects and large surface roughness Ra. However, the presence of reinforcing fibers and interfaces in the two types of composites can inhibit crack propagation or change their extension directions. Therefore, their surfaces are smooth and flat after grinding, with small defects and low surface roughness Ra. In addition, the grinding processes of the two composites are both related to fiber orientation. There are differences in crack propagation paths and fiber fracture positions in the weft fiber layer and the radial fiber layer, which result in different forms of grinding defects. During micro-grinding, the real-time force signals of 2.5D Cf/SiC composites and 2.5D SiCf/SiC composites are relatively stable, while the signals of SiC ceramics have a large number of spikes. The average micro-grinding force of the three materials is: SiC ceramics > 2.5D SiCf/SiC composites > 2.5D Cf/SiC composites. Full article
