Abstract
Magnesium-based bulk metallic glasses (Mg-BMGs) combine strength, low density, and tunable degradability. Their amorphous matrix has a small plastic process zone. This zone is only about 4 μm wide. A small process zone keeps most glasses brittle. Adding a second phase is the best fix. This chapter extends Mg-BMGs to true composites. We call these Mg-based bulk metallic glass composites, or Mg- BMGCs. The chapter covers matrix engineering and interfacial control. It also covers processing routes and toughening physics. Biomedical performance data for monolithic glasses are kept too. Continuous porous-metal skeletons are infiltrated under gas pressure. In Mg66Zn30Ca3Sr1, this raises compressive strength from 407 to 500 MPa. Plastic strain rises from 0.02% to 0.2% too. Copper plating on the skeleton improves wetting. Infiltration depth grows from 5 mm to over 30 mm. Dispersed particles use a different toughening route. TiB2 additions push fracture strength above 1.3 GPa. Plastic strain reaches 3.2% in these composites. Cu-coated SiC particles raise strength past 1.1 GPa. They work by blunting sharp particle corners. Porous NiTi dispersoids add a 12% strength gain. They also act as a corrosion barrier in Hank’s solution. The Halpin–Tsai model predicts composite modulus correctly. The simple rule of mixtures does not. The Mohr–Coulomb criterion explains the 41° shear angle seen here. A composition-only machine-learning model also predicts glass transition temperature well. Magnesium emerges as its single strongest elemental predictor. Matrix design and reinforcement design now work together. Together they push Mg-BMGs toward load-bearing implants.
