Experimental study on formability of bulk metallic glass as mold for microstructure replication

► The formability of La-BMG during imprinting is studied under different experimental conditions. ► A temperature of 155 °C, a time of 10 min and a load of 400 N are proved to be optimum imprint parameters. ► Correlation between time and Tg or Tx is positive while correlation between time and ΔT is negative. ► Formability and crystallized volume fraction of La-BMG are complex function of imprint parameters. ► La-BMG can replicate the patterns on Si-mold and transfer its own patterns on Ce-BMG and PMMA.
