About this Research Topic
One of the key driving forces for a sustainable long-term transportation strategy is lightweight construction of vehicle structures. Reducing weight, while at the same time retaining high strength and safety, remains an important goal in the development of future vehicle concepts. Magnesium, with its low density, good mechanical properties, and excellent castability and processability, is therefore an ideal material for manufacturers of all types of vehicles for the road, rail, aviation, and space. However, the most suitable material or material combination always depends on the particular application. This has made magnesium worthy of intensive research for alloys and new processing methods that are constantly being developed or optimized.
This Research Topic will summarize innovations in recent years in the field of magnesium research. Examples include alloy developments for casting and wrought applications, high temperature performance with good formability, and optimal corrosion resistance. Important issues for casting alloys include the formation of a specific microstructure in the casting by nucleation, grain refinement and grain growth, in addition to studies of hot tearing and casting defects. For wrought materials, the predominant topics are formability, phase and texture formation, and recrystallization. Specific mechanical properties acquired through the formation of special phases or other mechanical and physical properties that make the material more suitable for an application are also to be presented, as well as magnesium materials addressing a special function. These include biodegradable magnesium alloys for use as implants that, after some time, dissolve in the body. Another important focus is research in the fields of corrosion resistance and coating performance. Overviews of all casting and wrought processes, machining processes, welding and other joining processes, as well as the latest innovations in mechanical machining and additive manufacturing are to be included. The in situ observation of magnesium alloys, for example, to reveal their deformation or solidification processes by synchrotron or neutron radiation, is equally relevant as novel methods of using an electron microscope to identify the nanoscale structure. In addition to detailing the material science aspects, modelling and simulation approaches may also be included for all of these topics.
This Research Topic serves to mark the occasion of the retirement of Karl Ulrich Kainer, who has headed the Magnesium Innovation Centre (MagIC) at the Helmholtz Centre in Geesthacht for almost twenty years. During his tenure the entire value chain of magnesium as a structural material has been scientifically studied by the Institute. All current and former MagIC scientists are encouraged to submit papers. In addition, all project partners of the last twenty years and respected scientists of the magnesium community are also welcome to do so.
Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
