Abstract
In recent times, an alternative synthesis pathway involving severe plastic deformation for Mg-based materials has been explored involving the generation of turnings according to a set of machining parameters and cold compaction into billets followed by hot extrusion. This is known as the turning induced deformation (TID) method and has shown potential to alter the properties of resulting Mg-based materials for the better, not to mention economic benefits arising from this processing method. This work summarizes exploratory efforts involving this method for synthesis of Mg-based materials. The TID method resulted in overall superior properties compared to conventional processing methods, while two distinct parameters (high depth of cut and low cutting speed) were found to have significant positive influence on the final material properties, and as such are considered to be suitable basis on which further exploratory work in this field may be conducted.
Highlights
As a lightweight structural metal, magnesium (Mg) and its alloys have found applications in the engineering and biomedical industries [1,2]
As the generated turnings are obtained by localized plastic deformation on the Mgmaterial surface arising from the cutting motion [19], the turning induced deformation (TID) method, apart from its energy savings, has potential to alter and improve the properties of Mg materials based on existing knowledge surrounding processing of Mg using severe plastic deformation (SPD) techniques [17,20,21], where the extent of deformation during processing imparts superplastic properties on the material
It is of note that in this case, dry machining was done to generate the turnings, owing to the excellent machinability of Mg [26], ensuring that no additional decontamination or separation steps were required during consolidation of turnings, increasing the economic viability of this processing method
Summary
As a lightweight structural metal, magnesium (Mg) and its alloys have found applications in the engineering and biomedical industries [1,2]. While the resulting recycled Mg products from these studies show acceptable and even improved mechanical properties (especially with regards to tensile strength and in some cases, ductility), these solid-state recycling efforts only concerned Mg alloys and did not explore possibilities involving Mg nanocomposites or other novel materials. These prior efforts did not indicate plastic deformation on the recycled turnings as a factor in strengthening of the materials.
