1) Recent development of Surface Modification: from Nanostructure to Supra-Nanostructure
To develop high efficient and advanced energy system, the creation of new materials and associated systems is one of the key directions. This presentation will feature recent development of structural nanomaterials and high performance functional nanomaterials for the potential applications in mechanical and energy systems. The mechanisms of nanomaterials processing with different nano-structures by high efficient physical methods will firstly be reported by illustrating our latest findings / research progress on the nanomaterials with high strength and high ductility, nanostructure materials with gradient structure, hierarchical nano-twinned materials, nanomaterials with multiphase embedded structure and the supra-nanostructured materials. We will also present our recent work on an approach that combines the strengthening benefits of nano-crystallinity with those of amorphization to produce a dual phase material that exhibits near-ideal strength at room temperature and without sample size effects. The feasibility of applying different nanomaterials on various catalysis for splitting water (HER), light-weight vehicle and energy systems such as robotics in challenging environment (nuclear plant), ocean exploration and thermal energy conversion will be discussed. The application of new nanomaterials on the newly designed light-weight automotive parts and the development and research direction of the biomimetic morphing and 3D printed nanostructured materials on advanced aerospace and underwater vehicles systems will be presented.

1)Biomimetic methods and AI technics assisting Heat Treatment processes
Heat treatment is widely used in high value added technologies from a simple immersion quenching of gears up to the complex production technology of press hardening. The selection of process parameters to develop the desired properties is challenging due to the complexity of the physical phenomena occurring during the manufacturing cycle.
In the last decade several computational methods have been applied successfully to optimize the heat treatment processes. Among others, Biomimetic methods have been developed for solving complex and robust optimization problems on the field of casting, metal forming and heat treatment operations. These numerical methods are based on the emulation of the models, systems, and elements of nature for the purpose of solving complex human problems. These models have been inspired by structures and behavior of living creatures.
The development of computer modeling and simulation tools have led to great advances in understanding how materials behave during Heat Treatment operations. Unfortunately, high-fidelity computational simulations can take significant time to run and require large computational capacity. Process optimization requiring many simulations at different conditions can be expensive. To mitigate these obstacles to widespread use of sophisticated computer models, Artificial Intelligence methods based on neural networks could be support the Heat Treatment processes.
This paper is focusing on the state of the art of computational technics including Biomimetic methods and Artificial Intelligence approaches used to support Heat Treating Operations.

2)A study on the homogeneity of plastic deformation and its importance
to tensile ductility in Al-Si-Cu-Mg (C355) investment castings.
Alloy C355 was originally developed for aerospace applications and today finds utilisation in various aircraft components that operate at intermediate temperatures, such as aircraft superchargers covers, fuel pump bodies, compressor pistons, air or water-cooled cylinder heads, crankcases and various other applications where its high temperature resistance may be beneficial. Although the alloy is compositionally similar to other types of Al-Si-Mg-X alloys, a key difference comes about due to the presence of copper, which facilitates the formation of the Q/Q’ phase, (Al5Cu2Mg8Si6). The presence of this phase may facilitate unusual thermal stability under some conditions as the precipitate resists coarsening. Moreover, its microstructure can be tailored through precise heat treatment processes, making it even more versatile for a wide range of applications. However, C355 is also normally somewhat limited by the presence of Copper, and most specifications usually include typical elongation values of less than 4% (see for example AMS 4215 and AMS 21180).
Importantly, it has also been shown that alloys containing the Q/Q’ phase may display improved tensile ductility at room temperature when the composition is tailored to have an atomic ratio of Cu:Mg of close to 1:1. In the current paper, a hypothesis is investigated that may provide significant insight to the development of tensile mechanical properties in investment cast aluminium alloys. That is, by instituting a combination of good casting practice and alloy design together with heat treatments designed to promote homogeneous deformation, the usual limits of maximum ductility in Al-Si alloys might no longer apply. This may then mean that if deformation is particularly homogenous as a result, the material could keep necking to high elongations without unstable failure. As a result, ductility could significantly exceed the usual limits of Al-Si-X alloys. The current paper describes the outcomes of a study to investigate the abovementioned hypothesis. It will be shown that unexpected combinations of tensile mechanical properties may be realized, that include minimum values of elongation greater than 20% in C355 alloy while still maintaining compliance with manufacturing specifications.

3)Heat Treatment for Additive Manufacturing
Additive manufacturing (AM) is getting growing interest thanks to the possibility to produce complex three-dimensional parts directly from CAD models. Steel and non ferrous alloys in the as-built condition typically show a finer solidification microstructure respect to the same parts produced by conventional routes. Mechanical properties are also very attractive, provided that the microstructure is modified by suitable heat treatment and finishing. As a matter of fact, the elimination of post-heat treatment still represents a tough challenge for AM, due to the poor homogeneity of the solidification structure (e.g. microsegregation, anisotropy…) and the possible formation of hard and brittle phases. The intrinsic heat treatment taking place during 3D printing is difficult to be controlled, also in view of the more and more demanding productivity required by the industry. In most cases, a suitable heat treatment is necessary to improve the microstructure produced by rapid solidification, optimize the properties, and recover internal stresses.
In this work, the influence of heat treatments on the properties of some selected steels and non ferrous alloys produced by Laser powder bed fusion (LPBF) and Direct Energy Deposition (DED) is considered. Mention will be made also to DED repair of tools and dies. The results show that microstructure and properties like hardness, hot strength, fracture toughness, and thermal fatigue resistance can be tuned after suitable heat treatment.

4)Microstructure control of a medium manganese steel by combined interrupted
quenching and intercritical annealing
Fe-5Mn-0.1C alloy was subjected to interrupted quenching to a temperature between Ms and Mf followed by intercritical annealing in the ferrite and austenite dual-phase region. As a result, a core-shell type second phase, which consisted of a fresh martensite core surrounded by a film-like retained austenite shell, was formed. Characteristics of the microstructure and mechanical properties of the medium Mn steel with core-shell type second phase will be introduced.

6)Effects of laser peening on the very high cycle fatigue strength of additively
manufactured maraging steel
Recently, additive manufacturing (AM) has attracted interest as a new method
for manufacturing parts. However, defects easily occur during the AM process,
resulting in lower fatigue strength compared with the metals manufactured
by the conventional method. The internal defects significantly affect fatigue
strength in the very high cycle fatigue (VHCF) region exceeding 107 cycles.
However, the effects of mechanical surface enhancement technology on the
VHCF fatigue properties of AM metals are not clear. This keynote lecture
will provide an overview of the effects of shot and laser peening technologies
on the fatigue properties of AM metals. VHCF fatigue properties of AM maraging
steel subjected to laser peening will be presented.
