Special Issue Information

Dear Colleagues,

This Special Issue highlights pioneering advancements and transformative engineering applications of composite materials across aerospace, aeronautics, and maritime industries. It delves into the optimization of fabrication and processing methodologies for high-performance composites, revolutionary developments in multi-scale manufacturing techniques, and the mechanical resilience and performance evolution of lightweight structures subjected to extreme operational conditions, including high mechanical loads, corrosive environments, and thermal cycling. The scope encompasses the design, characterization, and deployment of fiber-reinforced polymers, ceramic matrix composites, and adaptive material systems, with emphasis on resolving fundamental challenges such as microstructural tailoring, interfacial engineering, and multifunctional hybridization. Submissions integrating experimental validation with advanced numerical modeling are particularly encouraged, such as studies elucidating damage propagation mechanisms, topology optimization for weight-critical designs, and next-generation non-invasive inspection protocols. A key focus lies on disruptive composite applications in next-gen aerospace propulsion, deep-sea exploration systems, and hypersonic platforms, fostering material-by-design paradigms that unify structural integrity with functional performance. This collective effort aims to catalyze theoretical breakthroughs in integrated material–structure–function frameworks, ultimately advancing the reliability, operational efficiency, and eco-conscious innovation of future transportation ecosystems.

This study investigates the effects of Hot Isostatic Pressing (HIP) treatment on the microstructural evolution and mechanical properties of Laser Powder Bed Fusion (LPBF)-manufactured Hastelloy H. This research evaluates the trade-offs between defect elimination, anisotropy reduction, and strength retention in well-optimized LPBF components. Specimens were manufactured using optimized LPBF parameters, achieving 99.85% density, and then subjected to HIP treatment at 1160 °C/100 MPa for 4 h. The analysis includes porosity analysis, grain size measurement, crystallographic texture evaluation, and tensile tests in two principal orientations. The results show that HIP treatment provides minimal benefits for defect elimination in already high-quality LPBF material, reducing porosity from 0.15% to <0.01%—a negligible improvement that does not translate to proportional mechanical enhancement. Tensile tests show that as-built specimens exhibited orientation-dependent strength, with XY-oriented samples reaching a yield strength (YS) of 682 MPa, ultimate tensile strength (UTS) of 864 MPa, and elongation of 17%, while XZ-oriented samples showed lower strength (YS = 621 MPa, UTS = 653 MPa) but superior ductility (elongation = 47%). After HIP treatment, anisotropy was largely removed, with both XY and XZ orientations showing comparable strength (YS ≈ 315–317 MPa, UTS ≈ 682–691 MPa) and elongation (38–41%). This indicates that HIP significantly improves ductility and isotropy at the cost of reduced strength. HIP treatment effectively eliminates the anisotropy of LPBF components, achieving uniform hardness across all orientations while reducing crystallographic texture intensity from 12.3× to 3.2× random orientation. This isotropy improvement occurs through grain-coarsening mechanisms that increase the average grain size from 7.5 μm to 13.5 μm, eliminating cellular–dendritic strengthening structures and reducing hardness by 32% (254 HV2 to 170 HV2) following Hall–Petch relationships. The conducted research confirms that HIP treatment allows for modification of the microstructure of Hastelloy X alloy, which may lead to the improvement of its mechanical properties in high-temperature applications and a significant increase in the isotropy of the material.
