Additive Manufacturing of Bulk Metallic Glasses and Their Composites – Recent Trends and Approaches

After attracting a lot of attention from the scientific community as advanced material
possessing superior properties of hardness, strength, and elastic strain limit, they have evolved as
composite material to overcome the problem of brittleness. Alloying elements are added to liquid melt
and with controlled conditions, they tend to form crystals in glassy matrix which serve above purpose.
Various primitive manufacturing methods such as rapid solidification in suction casting, twin roll
casting, film casting, spin casting and centrifugal casting have proved out to be their optimum method
of production. Additive manufacturing – a modern method is claimed to prosses inherent rapid cooling
rate which can be effectively utilized to make glassy structure. This short review details summary of
such recent attempts. It is found that method is beneficiary and effective.
