Hot rolling of bulk metallic glass in its supercooled liquid region

Large homogeneous strains as high as 1400% which are induced by strain rates of up to 70 s−1 are achieved by hot rolling Zr44Ti11Cu10Ni10Be25 in its supercooled liquid state. This technology permits us to create thin amorphous sheets with excellent surface finish and allows us to precisely replicate small features down to 300 nm in size.
