Special Issue Information

Dear Colleagues,

Metallic alloys used in aerospace construction form a class of materials that possess a great deal of variety in composition, properties, and applications that satisfy different requirements of lightweight, affordable cost, etc., and cover a range of service conditions, e.g., corrosion resistance, high-temperature stability under the conditions of oxidation and creep, fatigue resistance, stability of residual stress due to processing, etc. There is a vast amount of the literature devoted to the characterization of these alloy systems that on the one hand presents valuable reference information for design, and on the other, documents the established and new experimental approaches.

In recent years, the development of new solutions for aerospace alloys has been greatly accelerated, both in terms of predicting and refining novel systems, assessing their performance and structural integrity, and making new designs using these material systems. The diversity of aerospace alloys that already exist and are being developed presents unprecedented opportunities for the application of Artificial Intelligence as a means of optimizing properties and performance. Contributions are invited to this Special Issue that describe the use of Machine Learning and other big data processing techniques and evaluate their role in accelerating the emergence of new materials and engineering solutions in aerospace technology.

This Special Issue will include papers that report the advances in identifying new promising compositions and processing routes, along with the new methods of experimental assessment of properties and performance, and the interpretation of results to support rational alloy design.

In aeronautics, additive manufacturing (AM) leads to specific benefits, mainly connected to topological optimization for weight reduction, the decrease in “buy-to-fly” ratio, and the operations of maintenance, repair, and overhaul. Al alloys processed by AM technologies are extensively investigated and play an increasing role in the production of aircraft structural parts. Based on the recent literature and research activity of the authors, this work examines advantages and drawbacks involved in the printing of Al alloys. Defects, microstructure, mechanical properties, development of new alloys, and postprocess treatments are described and critically discussed by focusing the attention on the effects of the specific alloy composition, AM process, and process parameters.
