“…Méar et al [190] investigated Mg-based BMGs by ball milling Mg 55 Cu 30 Gd 15 and Mg 55 Cu 30 Y 15 (at.-%) gas atomised powders, for 18 and 30 h, respectively, to produce amorphous powder precursors for FAST. Fully glassy samples were successfully sintered at 125°C and Vickers hardness indents produced inhomogeneous plastic deformation.…”

The current status of field assisted sintering technology (FAST) of structural metals from powder is critically reviewed. Recently, there have been significant increases in the uptake of FAST for metallic systems, composites and porous materials at the laboratory-scale. It is clear that FAST is tolerant of powder/particulate feedstock, allowing rapid production of materials, some of which would be challenging through conventional sintering techniques. Yet, the underlying mechanisms allowing this are not fully understood. Final specimen sizes tend to be small, which restricts rigorous mechanical assessment. This review demonstrates the clear benefits in transitioning laboratory-scale demonstrators to the industrial scale over the next few years. However, consideration will need to be given to size, throughput, and shape complexities to attract commercial investment.

“…This opens up the possibility of preparing truly bulk samples through powder consolidation in supercooled liquid region. In the Zr-, Cu-, Fe-and Ni-based alloy systems, some successful consolidation of amorphous powders with wide supercooled liquid region has been achieved by warm extrusion, spark plasma sintering and equal channel angular pressing (ECAP) (Choi et al, 2007;Ishihará et al, 2002;Itoi et al, 2001;Karaman et al, 2004;Kawamura et al, 1997;Kim et al, 2009;Lee et al, 2003;Mear et al, 2009;Robertson et al, 2003;Senkov et al, 2004;Senkov et al, 2005;Sordelet et al, 2002;Zhang et al, 2006b;Zhang, et al, 2007a). The consolidated samples show almost the same thermal properties, mechanical properties, and/or soft magnetic properties as those of the BMGs prepared by direct melt casting from molted The data of the onset temperature of crystallization (T x ) and the glass transition temperature (T g ) at the heating rate of 0.67 K s -1 are also shown.…”

He obtained his B.Sc in physical chemistry from Bar-Ilan University in 1989 and received his PhD from the Weizmann Institute of Science with Prof. Gary Hodes on nanomaterials synthesis (1999). He then went to the Max Planck institute of colloids and interfaces for 3 years, as postdoctoral fellow to work with Prof. M. Antonietti and Prof. H Cölfen on biomimetic chemistry and chiral polymers. In 2003 joined the staff of the chemistry department at Bar-Ilan University, where he is currently a Professor at the institute of nanotechnology at Bar-Ilan University leading the nano chirality laboratory. Prof. Mastai's earlier interests included nanomaterials synthesis and characterization. His current research is focused on the synthesis and analysis of chiral nanosurfaces, chiral self-assembled monolayers and polymeric chiral nanoparticles. Mastai has published more than 100 scientific articles and book chapters on various aspects of nanomaterials and chirality at the nanoscale.XIV Contents I wish to thank all the authors for their contributions for this book and it is my pleasure to acknowledge the assistance of Ms Vana Persen for her assistance during the write-up of this book and is preparation in final format.Finally I would like to acknowledge my family who has supported me through all the years of doing science.

“…For this purpose, BMGs have recently attracted much attention for biomedical applications. BMGs such as Ti-based [1][2][3], Zr-based [4], Mg-based [5,6], and Ca-based [7] are popular in the biomedical field. Ti-based and Zr-based BMGs are almost impervious to corrosion in the human body; hence they are suitable for permanent implant.…”

“…And Mg-based and Ca-based BMGs for temporary due to be easily corroded by body fluids [5,7]. Compared to other materials, Mg is exceptionally light in weight with a density of around 1.74 g/cm 3 , and the elastic modulus of Mg is similar to that of natural bone [6]. Further, the ability for magnesium alloys to undergo biodegradation eliminates the requirement for a second surgery to remove the implant.…”

Mg and its alloys have attracted much attention recently as a biomaterial due to their excellent biocompatibility, similar mechanical properties to bone and biodegradability. However, the rapid degradation proved to be challenging to act as an implant. To improve the corrosion resistance and overcome rapid degradation of Mg-based alloys, researchers have been working on the synthesis of Mg-based bulk metallic glasses (BMGs). The first research on Mg-Cu-Y BMG was conducted by Inoue in 1991. Since then, Mg-based BMGs with different systems have been developed. Compared to the crystalline metallic Mg-based implants, the structure of Mg-based BMGs without any regular pattern offers low corrosion reactivity and increase passivity. Mg-based BMGs exhibit a good combination of biological, mechanical and corrosion properties and ease of fabrication. Thus, Mg-based BMGs can be considered an efficient candidate in the biomedical field.
