Abstract
- The purpose of this research is to produce high hardness of Mg from cutting chips using MM-SPS process. Effects of different starting materials, such as powder and cutting chips of Mg, on the properties were investigated. The influence of sintering holding times on the properties was also investigated to establish between the process conditions and the properties. Hardness testing and X-ray diffraction were carried out for characterization of powders and bulk materials. The results of hardness indicated that MM-SPS process can synthesis upgrade recycled material fabricated from Mg cutting chips. In the case of cutting chips, the maximum hardness was observed at 6 hours of MM and 60 min of sintering holding time. On the other hand, in the case of powder showed the maximum hardness at 6 hours of MM and 10 min of sintering holding time. However, the hardness did not increase with increasing sintering holding time. No solid-state reaction was observed in SPS materials fabricated from powder and cutting chips. In addition, no contamination of impurities during MM treatment was observed. [ABSTRACT FROM AUTHOR]
