Unveiling the Alloying-Processing-Microstructure Correlations in High-Formability Sheet Magnesium Alloys
نویسندگان
چکیده
Designing magnesium sheet alloys for room temperature (RT) forming is a challenge due to the limited deformation modes offered by hexagonal close-packed crystal structure of magnesium. To overcome this lightweight applications, critical understanding alloying-processing–microstructure relationship in needed. In work, machine learning (ML) algorithms have been used fundamentally understand correlations RT formability alloys. Three databases built from 135 data collected literature were trained using 10 commonly models. The accuracy model obviously improved with increase number features. ML results analyzed advanced SHapley Additive exPlanations (SHAP) technique, and descriptors are ranked as follows: (1) microstructure: texture intensity > grain size; (2) annealing processing: time temperature; (3) alloying elements: Ca Zn Al Mn Gd Ce Y Ag Zr Si Sc Li Cu Nd. Overall, intensity, most important factors which can be guide high-formability alloy design.

Formability of Magnesium Alloys
The paper is focused on issues of processing of non-ferrous metals in practice, namely on Mg-Al-Zn based on magnesium alloys with graded Al contents. It is well known that forming of these alloys is difficult since this feature is caused by their crystallographic arrangement. Nevertheless, application of appropriate methods of forming, such as e.g. some of SPD processes, makes it possible to ac...

Lightweight magnesium (Mg) alloys are being progressively incorporated into structural applications where weight reduction is an important design priority. Higher strength and better formability can be achieved by the development of new processing methods and new alloy composition, which entail a comprehensive understanding of the processing-microstructure-property relationship and deformation ...
متن کاملLaser Welding of Thin Sheet Magnesium Alloys
Magnesium and its alloys are active materials, and the oxide can easily form when they react with air and moisture (Czerwinski 2002). In addition, magnesium and its alloys are flammable and require strict safeguards during the manufacturing process. These disadvantages make the processing of magnesium alloys into finished products more challenging. These drawbacks cause defects such as cracks, ...
متن کاملMagnesium-based biodegradable alloys: Degradation, application, and alloying elements
In recent years, the paradigm about the metal with improved corrosion resistance for application in surgery and orthopedy was broken. The new class of biodegradable metal emerges as an alternative for biomedical implants. These metals corrode gradually with an appropriate host response and release of corrosion products. And it is absolutely necessary to use essential metals metabolized by hosti...
