Conventional and nonconventional methods for manufacturing the metallic glasses

What is it about?

Metallic glasses(MGs),first discovered in 1959 at Caltech are currently among the most studied metallic materials. MGs called also glassy metals, amorphous metals , liquid metals, are considered to be among the materials of the future. The “classic” methods for industrialization of MGs are : end-casting in copper molds and protected environment, die forging , atomization for obtaining MG powder ,selective laser melting , imprinting in molds, thermoplastic shaping in the supercooled temperature region. These methods are suitable for producing high value-added precision components but the problems still exists : expensive tools, limited lifetime of tools and the occurring of crystallization .

Why is it important?

Actually methods (thermoplastic shaping ,casting and die forging) are limited by the low flexibility of production and by higher costs of tools and accesories.
