On factors influencing the ductile-to-brittle transition in a bulk metallic glass
An experimental study to ascertain the ductile-to-brittle transition (DBT) in a bulk metallic
glass (BMG) was conducted. Results of the impact toughness tests conducted at various
temperatures on as-cast and structurally relaxed Zr-based BMG show a sharp DBT. The DBT
temperature was found to be sensitive to the free-volume content in the alloy. Possible
factors that result in the DBT were critically examined. It was found that the postulate of a
critical free volume required for the amorphous alloy to exhibit good toughness cannot …
